PHP Determining the current url

Question

I need to modify my function to return also the current folder I am in. Here is my current function:

function getLinkFromHost($url){  
    $port = $_SERVER[\         


        

Answer 1

Here a short sweet function I've been using to do this for awhile now.

function curPageURL() {
 $pageURL = 'http';
 if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
 $pageURL .= "://";
 if ($_SERVER["SERVER_PORT"] != "80") {
  $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
 } else {
  $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
 }
 return $pageURL;
}

I can't take the credit, it belongs to:
