NYCPHP Meetup

[Aaron Fischer]

I use the regexp from Chris's Essential PHP Security book:
http://phpsecurity.org/

$email_pattern = '/^[^@\s<&>]+@([ -a-z0-9]+\.)+[a-z]{2,}$/i';
if (preg_match($email_pattern, $yourEmailVar)) {
	echo 'It's good';
}
else {
	echo 'There's a problem';
}

Note, the echo's are thrown in for clarity, those aren't part of  
Chris's example code.  =)

Just ran it on your tom-cat example.  Passes through ok.
