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";
}
?> | |
