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's a method that might help:

function current_url()
{
    $result = "http";

    if($_SERVER["HTTPS"] == "on") $result .= "s";

    $result .= "://".$_SERVER["SERVER_NAME"];

    if($_SERVER["SERVER_PORT"] != "80") $result .= ":".$_SERVER["SERVER_PORT"];

    $result .= $_SERVER["REQUEST_URI"];

    return $result;
}
