Environment Variables

environment variables in PHP are treated as regular variables. This includes the environment variables that are set by the server for a CGI program. For example, if the url of your current page is "http://www.itechcollege.com/courses/PHP/12-Environment-Variables.php", which contains the code

<?php
echo $_SERVER['REQUEST_URI'];
?>

it prints out:

/courses/PHP/12-Environment-Variables.php
