Problem with preg_match

[TomH]

I'm making a newsletter script, this problem is beyond me.

The error is:

Warning: preg_match() [function.preg-match]: Compilation failed: unmatched parentheses at offset 123 in /newsletter.php on line 16

Line 16 -

if(preg_match('/\A(?:[a-zA-Z0-9]!#$%&\'+\/=?^{_{|}~-])+(?:\.[a-zA-Z0-9]!#$%&\'*+\/=?^_{|}~-]+)}@(?:a-zA-Z0-9?.))+(?:[a-zA-Z]{2}|com|org|net\b)\Z/i',$email)) return true;

Anyone help?

Count and match your parentheses.

You have one more ")" in your regex than you have "(". If you count up to the 123rd character of the regex (after the opening delimiter, you'll see the point where you have reached a situation of more ")" than "(".
