trza użyć curl'a:
<?php
function url_exists($url) {
// Version 4.x supported
$handle = curl_init($url);
if (false === $handle)
{
return false;
}
curl_setopt($handle, CURLOPT_HEADER, false);
curl_setopt($handle, CURLOPT_FAILONERROR, true); // this works
curl_setopt
($handle, CURLOPT_HTTPHEADER
, Array("User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.15) Gecko/20080623 Firefox/2.0.0.15") ); // request as if Firefox curl_setopt($handle, CURLOPT_NOBODY, true);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, false);
$connectable = curl_exec($handle);
curl_close($handle);
return $connectable;
}
?>
