I found this example in the php Manual and made some modifications.

<?
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 ;
    }
}

//Usage Example :
If(url_exists("http://www.weberdev.com/addexample.php3")) {
    Echo
"URL Exists";
}Else{
    Echo
"URL doesnot exist";
}
?>
