PHP preg_match prompt warning.
The code is as follows:
function Isvaliddomain ($domain) {
if (Preg_match ("/^ (HTTP|FTP)://(www\.)?". +\. (com|org|net) $/i ", $domain))
Return $domain. ' is a legal domain name ';
Else
return $domain. ' is not a legal domain name ';
}
Echo Isvaliddomain ("http://www.aixi.com");
?>
Operation Result:
