hey,

vielleicht hilft Dir ja folgende Fkt. weiter ...:

------------------
<?php

function phpLinkCheck($url, $r = FALSE)
{

$url = trim($url);
if (!preg_match("=://=", $url)) $url = "http://$url";
$url = parse_url($url);
if (strtolower($url["scheme"]) != "http") return FALSE;

if (!isset($url["port"])) $url["port"] = 80;
if (!isset($url["path"])) $url["path"] = "/";

$fp = fsockopen($url["host"], $url["port"], &$errno, &$errstr, 30);

if (!$fp) return FALSE;
else
{
$head = "";
$httpRequest = "HEAD ". $url["path"] ." HTTP/1.1\r\n"
."Host: ". $url["host"] ."\r\n"
."Connection: close\r\n\r\n";
fputs($fp, $httpRequest);
while(!feof($fp)) $head .= fgets($fp, 1024);
fclose($fp);

preg_match("=^(HTTP/\d+.\d+) (\d{3}) ([^\r\n]*)=", $head, $matches);
$http["Status-Line"] = $matches[0];
$http["HTTP-Version"] = $matches[1];
$http["Status-Code"] = $matches[2];
$http["Reason-Phrase"] = $matches[3];

if ($r) return $http["Status-Code"];

$rclass = array("Informational", "Success",
"Redirection", "Client Error",
"Server Error");
$http["Response-Class"] = $rclass[$http["Status-Code"][0] - 1];

preg_match_all("=^(.+): ([^\r\n]*)=m", $head, $matches, PREG_SET_ORDER);
foreach($matches as $line) $http[$line[1]] = $line[2];

if ($http["Status-Code"][0] == 3)
$http["Location-Status-Code"] = phpLinkCheck($http["Location"], TRUE);

return $http;
}
}
