In this tutorial, we will show you how to install and configure PHP 7 on your CentOS 7. 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. PHP 7 comes with numerous new and improved features. One of the most noticeable is the new Zend Engine version. Also, other important improvements are enhanced performance and significantly reduced memory usage. Thus, PHP 7 can be up to twice as fast as PHP 5.6.
This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple. I will show you the step-by-step installation of PHP 7 on the CentOS 7 server.

Step 4. Verify the Install PHP version.
Once it is completed, you can ensure that the latest stable release of PHP 7 is installed on your system by using the command:
# php -v PHP 7.0.0 (cli) (built: Dec 16 2015 20:42:32) ( NTS ) Copyright (c) 1997-2015 The PHP Group Zend Engine v3.0.0, Copyright (c) 1998-2015 Zend Technologies
To test PHP, create a test file named info.php with the content below. Save the file, then browse to it to see if PHP is working:
<?php phpinfo(); ?>
