Preventing Credit Card Fraud Using PHP and MYSQL Database in 2022



Credit card fraud has become widespread on the Internet. According to MasterCard International, there has been a 369% increase in account hijacking fraud since 1995. It has become one of the fastest growing and most difficult frauds to combat. More than $ 700 million in online sales was lost to fraud in 2001, according to GartnerG2, accounting for 1.14 percent of the total annual online sales of $ 61.8 billion. Even though the credit card company has given permission for the card’s expiration date, there are several ways to use fraudulent cards on your site. The card could have been lost or stolen, but the cardholder has not yet reported its loss. Or the number on the card (and not the card itself) could have been removed without the owner’s knowledge. There is also a fraud called theft, where a card is issued under a false pretense using someone else’s identity and data.

As an online merchant, you need a system to authenticate your placed orders to protect your business. While it may take extra time and money to do this, it can save you the cost and stress of fraudulent order chargebacks. You have lost your physical products; you lose the selling price; you are missing out on another business opportunity; and you will be fined an additional chargeback fee of $ 15-50. If you have a high chargeback rate, your card company might even blacklist you and void your merchant account. You will also take the time to search for the order and provide the requested information to your card service company. You can surely do without all of this annoyance.

How To Protect Your Business From Credit Card Fraud? Here are a few steps you can take to ensure that the transaction is being requested by the real cardholder.

Suspicious shipping address.

Orders from Ukraine, Indonesia, Yugoslavia, Lithuania, Egypt, Romania, Bulgaria, Turkey, Russia, and Pakistan have very high fraud rates and often have unverifiable addresses, according to ClearCommerce Corporation, a provider of payment processing and fraud protection software for e-commerce. …

Untracked email address.

In many fraudulent orders, the customer’s email address is often found in one of the free email services such as and, which are relatively untraceable.

Expensive things.

Beware of expensive orders, especially expensive branded items.

Several items.

This can be a bad sign, for example, if someone orders three X-Boxes or three DVD players at once, especially if the merchandise has a high resale value.

Express delivery.

Most fraudulent orders do not hesitate to include overnight or day delivery.

The shipping address is different from the billing address.

Pickup location and billing address are different for fraudulent claims. If you are selling valuables, it may be a good policy to only ship to the cardholder’s billing address.

Suspicious billing address.

The address looks too simple or invalid. If the billing address is 123 Main St, New York, the order is likely a scam. You can use either an online location tool to see if the address can be verified.

Leave at the door or in the mailbox.

If the courier service cannot guarantee delivery of the goods, the risk of fraud is very high.

The development of geo-targeting on the Internet allows us to precisely define the geographic region for the order. The information can be used to reduce fraud by verifying it against a billing and shipping address. This method can identify a scenario where someone from country X has stolen credit card information from country Y. The IP lookup service will show the real country instead of relying on the country filled out on the order form.

IP2Location ™ provides technology to translate an IP address to its country of origin. The lookup table is available in several formats such as database and COM. It is ideal for automating fraud detection using client-side programming languages ​​such as C ++ and Visual Basic; or utility programming languages ​​such as ASP, PHP, JSP, and CFML.

For example, company XYZ received an order for a credit card from the IP address The order details are as follows:

Name: John Ma

Address: 123 Main St

City: New York

Postal Code: 11111

Country: USA

Tel: (503) 111-1111

Credit card number: 1234 5678 9012 3456

Valid: December 2010

The credit card processor will authorize this order if the billing address matches the order details. Unfortunately, the credit card details were stolen earlier by Mr. Alphabet from another country via the Internet. Later, using this information, he made a purchase of digital products from XYZ Company. His order was approved by the seller because all the details matched John’s entry in the bank’s database. IP2Location ™ technology can pre-filter the difference between the country of order and the country of entry to protect your business. You can classify this type of order for manual check before delivery. You will be surprised how much this method will help in identifying fraudulent orders.

In this tutorial, we use the IP-Country IP2Location ™ database to find the country of origin based on the visitor’s IP address. Instead of downloading a complete database with over 50,000 entries, we could simplify this guide by assuming there are only two different IP ranges in the world. The IP addresses – come from the United States. Meanwhile, the IP addresses – come from Japan. Here we create a database “IP2Location” with a table “IPCountry” which consists of two IP address range entries.

Step 1. Create the IP2Location database and connect to it.

mysql> CREATE DATABASE IP2Location

mysql> CONNECT IP2Location

Step 2. Create the IPCountry table

mysql> CREATE TABLE IPCountry

-> (




-> countryLONG VARCHAR (100) NOT NULL,



Step 3. Import the ipcountry.csv database into the IPCountry table.

mysql> INSERT INTO IPCountry VALUES (0, 2130706431, ‘US’, ‘UNITED STATES’);

mysql> INSERT IN VALUES IPCountry (2130706432, 4294967295, ‘JP’, ‘JAPAN’);

The full version of the IP-Country Database is available for subscription for $ 49 / year at If you have a full version of the IP-Country IP2Location (TM) database, the import process will be much easier with the LOAD DATA function available in MYSQL.


We are creating a script to compare the country of the search and the data provided in the order authorization stream. It serves as a filter to reduce fraud. All rejected orders will be manually checked by sellers.

Important Performance Optimization Tips for Laravel Developers in 2022




Usage statistics published on various websites suggest that many web developers prefer Laravel over other PHP frameworks. Laravel’s expressive syntax makes it easy for developers to quickly write custom web applications. In addition, the platform accelerates the development of custom web applications by simplifying common web development tasks such as session management, routing, authentication, file system management, and unit testing. Laravel developers can further reduce web development by leveraging object-oriented libraries, command line interface, templating engine, ORM system, and queuing services.

Laravel is also constantly evolving to keep up with new trends in web development. For example, Laravel 5 comes with a redesigned directory structure, simplifies method injection and route caching, and supports multiple file systems natively. But built-in functions make Laravel slower than other PHP frameworks. Many developers even choose Lumen – a lightweight version of Laravel – to make their website run faster. Smarter Laravel programmers even optimize the performance of web applications using a number of best practices and tips.

7 Tips to Improve Performance and Speed ​​of Laravel Applications

1) Switch from lazy loading to active loading

The Eloquent Object-Relational Mapper (ORM) makes it easy for Laravel developers to work with multiple databases; perform create, get, update and delete (CRUD) operations; and map object models to database tables. But Eloquent ORM performs database operations based on a lazy loading approach. It does not retrieve data until it is explicitly referenced in the code.

The lazy loading approach negatively impacts website performance due to additional requests being made. Laravel developers can easily speed up a website by switching from lazy loading to eager loading. The eager loading approach retrieves the data along with the associated object models when the query is initially executed. Therefore, the web application can deliver data to the client faster without making additional requests.

2) Compress response data

By working with API-based frameworks, developers improve website loading speed by compressing response data. Laravel developers can easily speed up a web application by compressing the response data. They can take advantage of the Eloquent ORM to retrieve data to be displayed to the end user with a single query. But the extra data will affect website speed and increase bandwidth consumption.

Programmers can easily speed up a Laravel application by compressing the resulting data using view models. The view models will create multiple subsets of the data models and send the data item to the displayed user. Laravel even allows developers to compress response data and transform object model data using robust libraries like Fractal. Programmers can use Fractal to provide a presentation layer and transform the extracted data.

3) Use JIT compiler for Laravel

Often times, web developers use PHP compilers to compile PHP scripts into native machine code. The machine code runs smoothly on a computer without requiring a PHP interpreter. Smarter web developers use JIT compilers to speed up a web application by compiling PHP scripts once. Many programmers even compile PHP code using third party JIT compilers instead of Zend Engine.

Laravel developers can easily speed up web applications using an open source virtual machine like HHVM. HHVM uses a JIT compiler to quickly execute programs written in PHP and significantly improve the performance of a web application. However, HHVM currently supports the core functionality of PHP 7. Developers can use HHVM to speed up a Laravel application without additional time and effort.

4) Run Artisan Optimization Commands

Laravel 5 enables programmers to improve the speed and performance of applications by executing a set of commands. Developers can easily speed up a Laravel application by running commands to optimize the store path, compiling commonly used classes into one file, merging all configurations into one file, creating a route cache file, and compiling view files. Optimization teams also help programmers perform a number of mundane web development tasks.

5) Pre-compiling website resources

In a development environment, programmers make it easier to maintain websites by storing website resources in different files. Additional files often have a negative impact on website loading speed. Laravel developers can easily speed up a website by saving resources in fewer files when deploying an application. Laravel allows developers to pre-compile the efficiency of website resources using craft command line tools.

Programmers can run special commands to compile commonly used classes into a single file and combine configuration files and routes into separate files. Compiling and combining will help programmers speed up website loading. However, the effectiveness of the speed optimization method can differ from one website to the next.

6) Explore ways to implement caching

Laravel developers can easily speed up a web application by caching configuration and routes. They can even run artisan commands to cache the configuration and update the configuration when changes are made. Similarly, they can run the artisan command to move routes to the application controller, cache routes, and update route caches. At the same time, developers may also consider using a robust tool like Redis as a cache and session driver.

7) Remove unnecessary plugins and unused services

When using Laravel, programmers use plugins to add functionality to a web application without writing additional code. But due to these errors, the web application often downloads additional libraries and files. Developers can easily improve the performance of a Laravel application by removing unneeded plugins and trimming required plugins.

They can easily identify the providers loaded with the web application by accessing the config / app.php file. Similarly, they can run artisan commands to trim unneeded files and use composer to reduce dependencies when loading the application. Developers can even disable unused services in the config / app.php file to make the site load faster without affecting its functionality.

Overall, the features and tools provided by Laravel make it easy for programmers to create web applications to suit a variety of business needs. But they should learn ways to speed up the Laravel application to prevent user abandonment and improve the site’s search engine rankings. Laravel developers can easily optimize the performance and speed of a web application by implementing a few simple techniques and best practices.

Why Should You Choose Laravel For Your Next Web Project In 2022




When writing a web application in PHP, you have the option to choose from a wide variety of PHP frameworks. Usage statistics posted on several websites suggest that Laravel is currently more popular than other PHP frameworks. But smarter web developers never choose PHP based on popularity or market share. You must evaluate the pros and cons of Laravel in order to choose a PHP framework that fully meets all of your project’s needs. As an open source PHP framework, Laravel helps reduce the cost of developing web applications.

It further accelerates the development of custom web applications by providing a range of robust features and tools. At the same time, Laravel is constantly evolving to keep up with new trends in web development. Laravel 5.5 was released in September with a lot of new features – resource classes, automatic package detection, timed job attempts, on-demand notifications, and new frontend presets. You must understand the important features and tools provided by Laravel in order to decide if a PHP framework suits your project’s needs.

12 Reasons You Should Choose Laravel for Your Next Web Development Project

one) Intuitive syntax rules

Laravel’s syntax rules are simple and straightforward. You can learn the syntax of Laravel without wasting any extra effort or time. The syntax rules make it easier for you to maintain and update your Laravel application by writing clean code. In addition, Laravel’s syntax allows you to focus on the functionality and performance of the web application rather than its source code.

2) Composer

Using Laravel, you can improve the functionality of your web application and improve the user experience by using third party packages. Laravel also helps you manage the performance of external packages with a robust dependency management tool like Composer. You can even install and run Composer without any problems by running certain Artisan commands. But Composer will help you set up Laravel projects without downloading zip files and cloning Github packages. You even have the option to modify your composer.json file to quickly install the required packages.

3) Artisan

Laravel allows you to perform common web development tasks through the command line interface – Artisan. You can run Artisan commands to perform common web development tasks and optimize the performance of Laravel applications. At the same time, Laravel allows you to create your own commands according to your specific needs. You even have the option to create a new custom command by running the existing Artisan command, make: command.

4) Eloquent ORM

Laravel comes with a built-in object-relational mapping (ORM) system – Eloquent. You can use Eloquent ORM to work with multiple databases and perform general database operations. Using Eloquent ORM, you can efficiently work with multiple databases by implementing ActiveRecord. Likewise, you can use models to perform general database operations without writing long SQL queries. The database migration tool provided by Laravel further simplifies the process of synchronizing multiple databases running on different systems.

5) Blade templating engine

Because Laravel supports the Model View Controller (MVC) programming paradigm, you can quickly develop complex web applications by separating their user interface and business logic layers. At the same time, Blade’s templating engine helps you compile all views to PHP code, include PHP code in views, and cache PHP code until the views remain unchanged. You can even take advantage of the Blade templating engine to render data and extend layouts without affecting the performance of your Laravel application.

6) RESTful routing

In addition to simplifying the development of web applications, Laravel simplifies the development of web services by supporting RESTful routing. You can use PHP framework to create web services based on REST architecture. This feature allows you to force a web application to communicate with other applications and services over an open protocol such as HTTP. In addition, you can simplify the development of web services by using HTTP methods such as GET, POST, PUT, and DELETE.

7) Unit testing

Using Laravel, you can perform unit testing with PHPUnit. PHPUnit makes it easy to test specific functionality or functionality of a web application by performing unit testing throughout the development process. At the same time, Laravel allows you to perform unit testing simply by writing test cases and defining your own test methods. Hence, you can easily write and execute test cases according to your specific testing requirements.

eight) Authentication library

The authentication library provided by Laravel helps you secure your web applications by implementing various authentications. You can even control and manage individual authentication services simply by making changes to the authentication configuration file. In addition, you can take advantage of the security features provided by the Authentication Library to encrypt data, create login pages, and prevent cross-site request forgery (CSRF).

9) Caching system

In addition to providing a basic caching system, Laravel also supports widely used caching systems such as Redis, Memcached, and APC. You can take advantage of the underlying caching system to store objects in a database or file. In addition, you can run specific Artisan commands to cache configuration and routes. At the same time, you can easily speed up your Laravel application by replacing the underlying caching system with a robust third-party caching system such as Redis or Memcached.

10) Multiple file system

Laravel version 5 has built in support for multiple filesystems. You can use third party packages to work seamlessly with multiple filesystems. Laravel even allows you to customize the configuration using various options – config.php and filesystem.php. You even have the option to customize the configuration through both local and cloud storage. Native support for multiple file systems makes it easy to maintain API consistency by choosing the correct drive.

eleven) API development

The latest version of Laravel simplifies API development with resource classes. When writing APIs, you can use resource classes to bind Eloquent models and JSON queries without creating an extra layer of transformation. In addition, resource classes allow you to convert models and collections of models to JSON without requiring an additional level of conversion.

12) On-demand notifications

Laravel 5.5 allows for on-demand notifications to be sent to individuals who access a web application without registering. These people usually access the web application without logging in as users. Laravel developers can call the Notification :: route method to send on-demand notifications through the web application to those users by simply supplying custom notification routing information.

The robust features and tools provided by Laravel make it easy to create custom web applications to suit different business requirements. Additional features often negatively impact the performance of Laravel applications. Therefore, you need to implement a number of performance optimization techniques to speed up your application and improve the user experience. But Laravel is constantly evolving to keep up with new trends in web application development. You can always speed up your custom web application development by taking advantage of the new features and improvements included in the latest version of Laravel.

Ruby on Rails vs. PHP: Which One is Better? in 2022




Ruby on Rails vs. PHP: Which is Better?

First, let’s try to understand why you want to choose a particular technology. All technologies thrive on tools, developer communities, libraries, and applications. As a business owner, you may need technology that can work for years after starting a project.

As a developer, you need technology that you can maintain long enough to get a good return on your investment. Business owners or developers often make decisions with their peers and the developer community in mind, depending on the highly recommended technology.

In this post, we’ll take a quick look at the pros and cons of PHP and Ruby on Rails. We’ll see how PHP and Ruby on Rails can be compared with common issues like maintenance, performance, scalability, cost, and support.

Comparing PHP to Ruby on Rails is completely unfair. PHP is much more popular than Ruby on Rails because Ruby on Rails is a web development environment, not a programming language. Ruby is the language in which the Ruby on Rails framework runs on the back end, and PHP is the programming language used to code and build websites and web applications.

Ruby on Rails should be compared to Symfony2, Zend Framework, Codeigniter, Laravel, CakePHP and many other PHP-based web development frameworks. So, to understand why Ruby on Rails is so popular, it’s best to visualize human searches.

This trend graph from Google shows that all PHP web development frameworks still do not account for the number of searches performed for Ruby on Rails (highlighted in blue). In fact, the only web framework developing in the PHP world is Laravel. So why is Ruby on Rails so popular?

Well, a big part of building a web application is deciding which libraries you want to use, how to organize your web application, and many other factors. Today, many PHP projects still do not use a mature and proven web application development environment. Many PHP developers would prefer to create a new PHP framework instead of using the most popular frameworks like Zend Framework, Symfony2, etc.

Due to the complexity of the application, as with any framework, you will have to spend a lot of time learning how to use that particular framework. Thus, Ruby on Rails tries to make it easier to learn its structure by rejecting configuration by convention; In other words, you (a developer or business owner) have little time to decide when it comes to advertising, executing, or even hosting an application.

This may seem like a good idea, and for the most part it is, which is why Ruby on Rails is very popular. However, since then, many PHP web application development environments have recognized this and follow the steps of Ruby on Rails web development. This could be the reason why the growth of the Ruby on Rails community has stalled in recent years. Now, while other web development frameworks are shown in small percentages, you should still remember that PHP is completely web-centric. Thus, almost everything you write in PHP will work on the web, while in Ruby you don’t have many options for what code you can write to develop a web application.

1. Scalability and ease of maintenance

Whether it’s PHP or Ruby on Rails, both offer scalability. However, due to the amount of resources Ruby uses compared to PHP, scalability issues will arise much earlier in the lifecycle of your application. Scaling a Ruby on Rails application over PHP will solve very common problems. So the scale will depend on how the application was designed. There are also online services available to help solve scaling issues such as using Rackspace Cloud Sites or Amazon Elastic Beanstalk.

The situation becomes very different when you go from wanting to climb to needing to climb. When a developer is inexperienced in scaling an application, the most common way is to search for online articles, tutorials, and other resources to learn. So when we talk about scaling a website, there are many resources written and available for PHP developers, while Ruby on Rails has a much smaller development team.

As far as ease of maintenance is concerned, it depends entirely on the organization of the web application. As long as a web developer uses a web development framework, overall maintenance becomes much easier. PHP offers a huge selection of web development frameworks, each of which is tailored for a specific purpose, while Ruby has a limited selection (other than Ruby on Rails).

2. Speed ​​and performance

Since PHP is a programming language and Ruby on Rails is a web application development environment, you should take performance with a grain of salt. The goal of using a complete web development environment is to improve performance at the expense of speed. So let’s clear this up a bit.

Here is a table for a very simple hello world web application. Below you can see how fast PHP is when it comes to requests: remember, this is a language designed specifically for the web. However, once you start implementing popular frameworks for developing full-featured web applications, performance drops and requests per second approach Ruby on Rails.

In fact, the famous PHP Laravel web development framework starts to perform worse than Ruby on Rails. As a result, many tests are useless because the speed and performance of a web application is much greater than the language or web development environment. For example, network latency, database system, and caching mechanisms can increase the slowdown from 10x to 100x. So, how the design of the application is much more important than the programming language or the web development framework that underlies it.

3. Cost

Scarcity is a fundamental concept in economics. So, if you have 10 PHP web developers for every Ruby web developer, and the project function is language dependent, there will be a clear cost winner. PHP has lower prices due to strong competition. If your motive as a business owner is based on cost, this should be a very rewarding incentive. There is a saying, “You get what you pay for,” but that doesn’t mean you have to pay the same amount for the experience available. PHP has a very easy learning curve. In addition, many PHP developers are new to programming in general and web application programming in particular.

See also  Top 10 Reasons to Choose Laravel for Your Next Web Application Development Project in 2022

On the other hand, Ruby is a more difficult language to learn, so people who choose this language already know how to program. It is natural for a PHP developer to switch to Ruby on Rails and have experience translating PHP to Ruby around the world. In fact, many Ruby developers were PHP developers. So why are developers switching to Ruby on Rails? Well, this answer will be the same for almost any other programming language besides PHP.

In any language other than PHP, the language will restrict it in the code you can write, as well as in what is available for use. Thus, it is becoming a common method of creating web applications in this language. For example, C # has ASP.NET, Python has Django, Node.js has Express, Lua has Orbit, and the list goes on. So to put this in perspective, let’s say you’ve had the opportunity to interact with a massive audience or be among a select few professionals who share the same goals. It would make sense for the most recognizable applications to be built in languages ​​that have the largest audience, hence PHP is the target language. Applications such as WordPress, Drupal, Magento, Facebook are just a few of the many PHP applications available.

When it comes to hosting your Ruby on Rails applications, costs can go up very quickly. You will have a harder time finding hosting that supports your Ruby on Rails application, and big brands are not cheap. They start at $ 40 and quickly jump to $ 500 or more. There are even some companies that offer free housing, but they will charge high fees when they need to expand their housing needs. Almost all hosting companies offering Ruby on Rails hosting also provide PHP hosting. Some of the cheapest hosting providers offer old and outdated versions of Ruby (language), which limits you to previous versions of Ruby on Rails. They also run their Ruby on Rails app as CGI, which is the slowest way to run your web app.
