[SOLVED] how to determine domain/url of page

[dsaba]

Let's say you have a link that is really a redirect link:

http://tinyurl.com/1c2

 

this redirects to the url: http://www.google.com, but let's say you didn't know this, and wanted to find out.

 

How would you do this, are there any php functions that can help determine the url or domain you are on once you have visited or requested a webpage? ie: with file_get_contents() ....

 

I was thinking parse the html contents for hints, but let's say the mystery url does not have its url anywhere in its source

Without cURL:

<?php
//array stream_get_meta_data  ( resource $stream  )
$handle = fopen('http://tinyurl.com/1c2','r');
$arr = stream_get_meta_data($handle);
echo '<pre>';
print_r($arr);
echo '</pre>';

fclose($handle);
?>

 

outputs:

Array

    [wrapper_data] => Array
