Parse final domain from redirect link.

guest · 06-02-2011, 06:53 AM

I have a collection of redirect links I need to grab the final domain from (indicated after "->"):

http://www.shareasale.com/u.cfm?d=60...28411&u=503118 -> priceangels.com
http://scripts.affiliatefuture.com/A...tracking=&url= -> letsgostrolling.com

I'm thinking PHP/cURL is the way to do it. I've searched the net but failed to find a solution that works for all redirection links. Any help is greatly appreciated!

I recommend using wget for this. Supply the URL or URLs as command-line parameters for this scriptlet:

Code:

#!/bin/bash
while [ $# -gt 0 ]; do
    wget -vO /dev/null "$1" 2>&1 | sed -ne 's|Connecting to \([^|]*\).*$|\1|p' | tail -n 1
    shift 1
done

Found a solution but the code spits out a bunch of other info among the final url. Is there a way to just get the final url destination out of this garble?

Code:

<?php
function getWebPage($url, $redirectcallback = null){
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, false);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_NOBODY, false);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Macintosh; U; Intel Mac OS X; en-US; rv:1.8.1) Gecko/20061024 

BonEcho/2.0");

    $html = curl_exec($ch);
    $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    if ($http_code == 301 || $http_code == 302) {
        list($httpheader) = explode("\r\n\r\n", $html, 2);
        $matches = array();
        preg_match('/(Location:|URI:)(.*?)\n/', $httpheader, $matches);
        $nurl = trim(array_pop($matches));
        $url_parsed = parse_url($nurl);
        if (isset($url_parsed)) {
            if($redirectcallback){ // callback
                 $redirectcallback($nurl, $url);
            }
            $html = getWebPage($nurl, $redirectcallback);
        }
    }
    return $html;
}

function trackAllLocations($newUrl, $currentUrl){
    echo $currentUrl.' ---> '.$newUrl."\r\n";
}

print htmlentities(getWebPage('http://www.shareasale.com/u.cfm?d=60472&m=28411&u=503118'));

//$myUrlInfo = parse_url( $thisurl ):
//echo $myUrlInfo["url",track];
print $myUrlInfo[$url];
?>
