PHP is a popular scripting language for developing dynamic web applications. With its flexible syntax, support for multiple frameworks, and a vast library of pre-built functions, PHP has become a go-to language for developers. However, like any programming language, it has its own set of best practices that developers must follow to ensure their code is secure, scalable, and maintainable. In this article, we will discuss PHP development best practices.

Use a Framework

One of the most important best practices for PHP development is to use a framework. A framework is a set of libraries and tools that provide a structure for developing web applications. Using a framework can save you a lot of time and effort as it comes with pre-built functions, libraries, and tools for common tasks. Some popular PHP frameworks include Laravel, Symfony, and CodeIgniter.

  • Use PDO instead of MySQLi

PHP has two libraries for interacting with MySQL databases, MySQLi, and PDO. PDO (PHP Data Objects) is a more flexible and secure way of interacting with databases. PDO supports multiple databases, including MySQL, PostgreSQL, Oracle, and more. It also has built-in support for prepared statements, which can help prevent SQL injection attacks.

  • Use Prepared Statements

Prepared statements are a powerful tool for preventing SQL injection attacks. Prepared statements are a way of passing parameters to a database query separately from the SQL statement itself. This way, the database can distinguish between the SQL code and the data being passed to it. Prepared statements are supported by most databases, including MySQL, PostgreSQL, and Oracle.

  • Validate User Input

Validating user input is essential to prevent malicious attacks on your web application. Attackers can use various techniques to inject malicious code into your application, such as SQL injection or cross-site scripting (XSS). To prevent these attacks, you should always validate user input and sanitize it before using it in your application.

  • Use HTTPS

HTTPS (Hypertext Transfer Protocol Secure) is a protocol for secure communication over the internet. Using HTTPS can help protect sensitive data transmitted between the web server and the client. HTTPS uses SSL/TLS certificates to encrypt data and prevent eavesdropping and tampering. You should always use HTTPS in your web application, especially if it involves sensitive information such as passwords, credit card details, or personal information.

  • Use Composer for Package Management

Composer is a dependency manager for PHP that allows you to manage packages and libraries for your project. It allows you to easily install, update, and manage dependencies for your project. Composer also ensures that all the required dependencies are installed and up-to-date, making it easier to manage your project.

  • Use PSR Coding Standards

PSR (PHP Standard Recommendations) are a set of coding standards that are widely adopted in the PHP community. Using PSR coding standards ensures that your code is consistent, easy to read, and maintainable. It also helps to ensure that your code is compatible with other PHP libraries and frameworks.

  • Use an IDE

Using an IDE (Integrated Development Environment) can make your development process much easier and efficient. IDEs provide features such as code highlighting, auto-completion, and debugging, making it easier to write and debug your code. Some popular PHP IDEs include PhpStorm, Eclipse, and NetBeans.

  • Use Version Control

Version control is essential for any software development project, including PHP development. Version control allows you to keep track of changes made to your code and collaborate with other developers. Git is a popular version control system that is widely used in the PHP community.

  1. Test Your Code

Testing is an essential part of software development, and PHP is no exception. Testing your code helps to ensure that it is free of bugs and works as expected. There are several types of tests you can use for PHP development, including unit tests, integration tests, and acceptance tests. Unit tests are used to test individual units of code, while integration tests test the interaction between different units of code. Acceptance tests are used to test the overall functionality of the application.


In conclusion, PHP is a powerful and flexible language for developing web applications. However, it is important to follow best practices to ensure that your code is secure, scalable, and maintainable. Using a framework, PDO, prepared statements, validating user input, using HTTPS, Composer, PSR coding standards, an IDE, version control, and testing are some of the best practices that you should follow for PHP development. By following these best practices, you can ensure that your PHP code is of high quality and meets the needs of your users.
