PHP is a widely used open-source general purpose scripting language that is especially suited for web development and can be embedded into HTML.

To install php, open terminal and type in this command:

yum install php php-mysql php-gd php-pear -y

You can install multiple libraries at once by separating the name of each module with a space.

Test PHP:

Create a sample “test.php” file in Apache document root folder and append the lines as shown below:

vi /var/www/html/test.php

Add the following lines.

<?php 
phpinfo(); 
?>

Then Save and Exit.

Restart apache so that all of the changes take effect on your virtual server:

service httpd restart

Now you can access your php info page http://IP/test.php. It will display all the details about php such as version, build date and commands etc.
