PHP: get relevant URL of the current page using $_SERVER array
$_SERVER array in PHP stores server and execution environment information.
In PHP project development, we often need to get some of the relevant URL of the current page using $_SERVER array.

Note:
difference between $_SERVER['SERVER_NAME'] and $_SERVER['HTTP_HOST']
For: http://localhost:8083
$_SERVER['SERVER_NAME'] returns localhost, while $_SERVER['HTTP_HOST'] returns localhost:8083.
