PHP Function: How To Get The Current Page URL (Address Bar Link)

There are number of times when we need to play with PHP and the pre-defined constants and variables. PHP has a vast number of methods which can help us in dealing with almost all issues. Today, I am gonna share with the trick to find out current page’s URL, yes the link that you see in your browser’s address bar.

Here is  the code:

    function getCurrentPageUrl(){

        //All URLs start with http: followed by 's' (in case of https)
        $currentPageURL = 'http';

        //check if the server is https based
        if ($_SERVER["HTTPS"] == 'on') {
            //attach extra 's' for https based URLs
            $currentPageURL .= 's';
        }

        //attach characetrs needed to form a valid URL
        $currentPageURL .= '://';

        //get full script URL from SERVER array
        $currentPageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];

        //return the exact current page URL
        return $currentPageURL;
    }

    //Usage:
    echo getCurrentPageUrl();

The above code works for both http and https based URL’s. To find out more about URL’s, look at here.
