PHP Determining the current url

问题

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['REMOTE_PORT'];  
    $server = $_SERVER['HTTP_HOST'];  
    if($port == 443){  
        $type = "https";  
    } else {  
        $type = "http";  
    }  
    return $type . "://" . $server . "/" . $url;  
}

回答1:

Take a look at $_SERVER['REQUEST_URI'] or $_SERVER['SCRIPT_NAME']

(From the $_SERVER manual entry)

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:

Probably you also want to include get vars into your url, so you should add something to highphilosopher function...

$current_url = rtrim(curPageURL(), "/").(!empty($_GET)) ? "?".http_build_query($_GET) : "";

..........

echo $_SERVER['PHP_SELF']; // return current file

echo __FILE__; // return current file

echo $_SERVER['SCRIPT_NAME']; // return current file

echo dirname(__FILE__); // return current script's folder

// etc

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;
}
