How To Install PHP 5.5 on CentOS

Install PHP 5.5 on CentOS

In this tutorial, we will show you how to install PHP 5.5 on CentOS. For those of you who didn’t know, PHP (PHP: Hypertext Preprocessor) is a server-side scripting language designed for web development but also used as a general-purpose programming language. PHP code is interpreted by a web server with a PHP processor module, which generates the resulting web page: PHP commands can be embedded directly into an HTML source document rather than calling an external file to process data.
