Thread: Warning Unknown modifier

Warning Unknown modifier
Warning: preg_match() [function.preg-match]: Unknown modifier '@' in class_main.php on line 124

PHP Code:
if (!preg_match("^[^@]{1,64}@[^@]{1,255}$", $email)) {

Anyone can please help me to solve my warning.

Try this

Code:

"/^[^@]{1,64}@[^@]{1,255}$/"

The first character tells PHP which character to as the modifier. In your case, ^ is that character, so @ (and possibly the rest of the string) is treated as a modifier. There is, however, no modifier @, so you get an error. By adding / to the front, / becomes the modifier.
