CURL: Get final URL after inital URL redirects

[zebe]

Hi,

 

I need to find the redirected or 'final' URL of an initial URL which has a 302 redirect in it.

 

User goes to: www.1.com and gets redirected to www.2.com, I need to get 'www.2.com'

 

I think this can be done using CURL. Here's what I have so far, which is returning the original link...

 

/*
* Get a web file (HTML, XHTML, XML, image, etc.) from a URL.  Return an
* array containing the HTTP server response header fields and content.
*/
function get_web_page( $url )
{
    $options = array(
        CURLOPT_RETURNTRANSFER => true,     // return web page
        CURLOPT_HEADER         => false,    // don't return headers
        CURLOPT_FOLLOWLOCATION => true,     // follow redirects
        CURLOPT_ENCODING       => "",       // handle all encodings
        CURLOPT_USERAGENT      => "spider", // who am i
        CURLOPT_AUTOREFERER    => true,     // set referer on redirect
        CURLOPT_CONNECTTIMEOUT => 120,      // timeout on connect
        CURLOPT_TIMEOUT        => 120,      // timeout on response
        CURLOPT_MAXREDIRS      => 10,       // stop after 10 redirects
    );

    $ch      = curl_init( $url );
    curl_setopt_array( $ch, $options );
    $content = curl_exec( $ch );
    $err     = curl_errno( $ch );
    $errmsg  = curl_error( $ch );
    $header  = curl_getinfo( $ch );
    curl_close( $ch );

    //$header['errno']   = $err;
   // $header['errmsg']  = $errmsg;
    //$header['content'] = $content;
print($header[0]);
    return $header;
}

 

Anyone know how I can modify this function to get the final redirected URL result?

 

Thanks so much for the help. I really appreciate it.
