Help with regular expressions

Anon

I'm working on a script that will validate a form, and the only thing I'm stuck on is the e-mail address... I found several different regexp patterns out there for matching e-mail addresses, but either they don't work (less likely) or my script is wrong (more likely). Can anyone help me out? Here's my function:

function check_email($email) {

global $errors;

$pattern = "^(0-9a-z]+)([0-9a-z\.-_]+)@([0-9a-z\.-_]+)\.([0-9a-z]+)$";
if ($email == "") {
	print "<b><font color=red>E-mail Address may not be blank.</font></b><br>\n";
	$errors = "Y";
	return false;
} else if (!eregi($pattern,$value)) {
	print "<b><font color=red>E-mail Address is invalid.</font></b><br>\n";
	$errors = "Y";
	return false;
} else {
	return true;
}

}

And here's the form page:

Any help would be appreciated. Thanks!

I think your problem is on this line:

$pattern = "^{(0-9a-z]+)([0-9a-z.-]+)@([0-9a-z.-]+).([0-9a-z]+)$";}

For one thing, your brackets don't match up. Probably a typo.

Check out the article on this site about regular expressions. It's toward the bottom of the list of articles. if I remember right, it gives an ereg check for email addresses.

Hmmm... I replaced the pattern with the one on the page you mentioned, (http://www.phpbuilder.com/columns/dario19990616.php3?page=3) but it still doesn't work. Any other ideas?

DUH! I'm an idiot. I was testing the pattern on a different variable than what was being passed to the function - a result of cutting and pasting from my other functions. Don't I feel like a jackass? Thanks for the help!
