The phpinfo() function is a very useful PHP function for viewing detailed information about the PHP environment, including PHP configuration options, loaded extension modules, etc. It can output this information in the form of HTML pages. This article will show you how to use the phpinfo() function to view enabled modules.
First, let us understand how to use the phpinfo() function. Insert the following code in your PHP file:
phpinfo(); ?>
Save this code as a PHP file and upload it to your web server. When you access this file, you will see a detailed PHP information page.
This information page lists a lot of information about your PHP environment, including PHP version, server information, operating system information, and various configuration options. At the bottom of this page you will find a "Loaded Modules" section, which lists the enabled extension modules.
The Loaded Modules section shows all the modules that are enabled in your PHP installation. The name of each module and The module's description will appear in the list. The list may vary between different PHP versions and server configurations.
Here are some common examples of enabled modules:
1 . Core: This is the core module of PHP, providing the basic functions of PHP.
2. PDO: The PHP Data Objects (PDO) module is a lightweight database abstraction layer that allows a unified interface Access different types of databases.
3. MySQLi: MySQL The Improved (MySQLi) module is an interactive extension between PHP and MySQL database, providing more functions and security. It is an upgraded version of the traditional MySQL module.
4. GD: The GD module is a graphics library for creating and manipulating images in PHP.
5. OpenSSL: The OpenSSL module is an open source encryption toolkit that provides encryption, decryption, and signature functions.
This is just a small sample of enabled modules. The actual list you see on your server may be longer and may have different modules depending on your PHP version and your server configuration.
One of the benefits of using the phpinfo() function is that it provides a quick and easy way to view the loaded modules in your PHP environment. This is very helpful in understanding the capabilities of your server and what is possible with your application.
To summarize, the phpinfo() function is a powerful tool that can help you view the details of your PHP environment, including enabled modules. Understanding this information is important for diagnosing problems, determining server capabilities, and developing applications. Therefore, I recommend you to use the phpinfo() function whenever you need to know the details of your PHP environment .
