Get more details : Get current page URL in PHP

In this tutorial, we are going to discuss how to get current page URL using PHP. $_SERVER is a super global variable, which is always available in all scopes. We will use $_SERVER variable to get the current page URL. It is an array contains various information such as, headers, document path, script location, request method etc.

Explanation about some useful $_SERVER variable :
$_SERVER['HTTP_HOST'] : Contents of the Host header from the current request, if there is one.
$_SERVER['PHP_SELF'] : The filename of the currently executing script, relative to the document root. For instance, $_SERVER['PHP_SELF'] in a script at the address http://skptricks.com/post/php-tutorial.php would be /post/php-tutorial.php.
$_SERVER['QUERY_STRING'] : If a page is accessed via any query string, $_SERVER['QUERY_STRING'] fetches that query string.This is a actual URL http://localhost/skptricks/check current page url/currentPageURL.php?jj=kkkk after the $_SERVER['QUERY_STRING'] operation would be jj=kkkk .
