How can I convert ereg expressions to preg in PHP? (4 answers)
Closed 2 years ago.
I'm sorry to ask a question but I am useless when it comes to understanding regex code.
In a php module that I didn't write is the following function
function isURL($url = NULL) {
if($url==NULL) return false;
$protocol = '(http://|https://)';
$allowed = '([a-z0-9]([-a-z0-9]*[a-z0-9]+)?)';
$regex = "^". $protocol . // must include the protocol
'(' . $allowed . '{1,63}\.)+'. // 1 or several sub domains with a max of 63 chars
'[a-z]' . '{2,6}'; // followed by a TLD
if(eregi($regex, $url)==true) return true;
else return false;
}
Can some kind soul give me the replacement code for that with whatever is required to replace the eregi
