PHP modules Shared and Reseller hosting servers

PHP is a widely-used, open-source scripting language, which is especially suited to web development. It can be deployed on most web servers on almost every OS and platform, free of charge. PHP is at the core of the most popular blogging system on the web – WordPress. Did you know that even Facebook is running on PHP?

Originally, PHP stood for Personal Home Page. Nowadays, it is an acronym for “PHP: Hypertext Preprocessor.”

PHP code is usually processed on a web server (for example, Apache) by a PHP interpreter, which is implemented as a module, a daemon, or as a Common Gateway Interface (CGI) executable.

PHP extensions (modules) are specially formed libraries or plugins. They are usually written in C and then compiled to native machine code. There are core, bundled, and external extensions. You can check them on this page.

When using PHP extensions, you can avoid recreating the same code for numerous applications. You can also make use of an extension to:

• Provide functions and/or classes to work with data structures such as strings, arrays, objects, lists, and graphs
• Implement bindings to some external libraries (for example, POSIX regular expressions or simplexml)
• Connect to databases, such as PostgreSQL or MySQL
• Increase the security of your site, app, or any other code, using Hashing or data encryption by such technologies, like OpenSSL, Sodium
• Facilitate processes with external services via technologies (for example, XML-RPC and SOAP)
• Add caching, debugging, profiling, and testing capabilities to your application

To use an extension, you connect it to your application’s PHP binary.

To enable a particular PHP module on your Shared or Reseller hosting, you can check this guide. If a particular module is not supported in the PHP version you are using, you can change it according to this tutorial.

Below are brief descriptions of the modules:
