[SOLVED] Checking valid e-mails using regex?

[Wolphie]

Does anybody know how to check e-mails using regex.

 

E.g. i have a text box where somebody inputs an e-mail address. And if it doesn't contain certain e-mail address formats then return an error message.

 

Characters such as "@" or "."

Here's a builtin way:

if (filter_var($email, FILTER_VALIDATE_EMAIL))	//	builtin php func!

and here's a regex way I use (it may need ammendment still, but it also catches one's the other doesn't):

function scheck_email($email)
{
if(!eregi("[A-Z0-9._%-]+@[A-Z0-9.-]{2}([A-Z0-9.-])?\.[A-Z]{2,4}",$email))
	return -1;	//	invalid
return 1;		//	valid
}

Hmm, this works on my local server but not on my web server. The built-in function i mean.

Warning

 

Windows versions of PHP prior to PHP 4.3.0 do not support accessing remote files via this function, even if allow_url_fopen is enabled.
