OK guys,

Just in case you are interested, I found a faster solution than fopen()

--------------------------------------------------------------------------------------------------
<?
function url_exists($strURL) {
    $resURL = curl_init();
    curl_setopt($resURL, CURLOPT_URL, $strURL);
    curl_setopt($resURL, CURLOPT_BINARYTRANSFER, 1);
    curl_setopt($resURL, CURLOPT_HEADERFUNCTION, 'curlHeaderCallback');
    curl_setopt($resURL, CURLOPT_FAILONERROR, 1);

    curl_exec ($resURL);

    $intReturnCode = curl_getinfo($resURL, CURLINFO_HTTP_CODE);
    curl_close ($resURL);

    if ($intReturnCode != 200 && $intReturnCode != 302 && $intReturnCode !=
304) {
       return false;
    }Else{
        return true ;
    }
}

//need here because it spills all kinds of crap
ob_start();

//Usage Example :
If(url_exists("http://www.weberdev.com/addexample.php3")) {
    ob_end_clean();   // need to clean returned crap and start printing your
stuff
    Echo"URL Exists";
}Else{
    Echo"URL doesnot exist";
}
?>
-----------------------------------------------------------------


Thanks,

Néstor :-)
