<?php
function gsb($string, $start, $end)
{
    $string = " " . $string;
    $ini    = strpos($string, $start);
    if ($ini == 0)
        return "";
    $ini += strlen($start);
    $len = strpos($string, $end, $ini) - $ini;
    return substr($string, $ini, $len);
}
$homepage = file_get_contents('http://remotehost.com/iframe.php');
$link="http://mywebsite.com/".gsb($homepage,"window.open('","'");
echo $link;
