[RESOLVED] ereg vs preg_match

[dsp77]

i have this function here:

    function validateEmail($email){
        return ereg("^[a-zA-Z0-9]+[a-zA-Z0-9_-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$", $email);
    }

ereg is deprecated and i don't know how to use preg_ instead any help?

    function validateEmail($email){
        return preg_match("/^[a-zA-Z0-9]+[a-zA-Z0-9_-]+@[a-zA-Z0-9]+[a-zA-Z0-9.-]+[a-zA-Z0-9]+.[a-z]{2,4}$/", $email);
    }

There's more to preg_match than that ... but this will return TRUE/FALSE ... which is what you want.

Then again, that regexp rejects valid e-mail addresses while allowing invalid ones, so you should probably just ditch it altogether and use something like [man]filter_var/man with the FILTER_VALIDATE_EMAIL flag.
