Email Feild Auth

[fean0r]

I have been trying to pout together a simple function to check the email field has been used and it is valid.

I found a longer function which I simplified to this, does this need improving?

function c4emailchk($email) {
 if (preg_match('/^\w[-.\w]*@(\w[-._\w]*\.[a-zA-Z]{2,}.*)$/', $email, $matches)) {
 return true;
 }
 return false;
}

Thanks!

there is the useful filter functions in php5

if(filter_var($email,FILTER_VALIDATE_EMAIL)

I believe the applicable standard(s) allow for email addresses which would be flagged as invalid by your function. For a good PHP-related article on the subject, see http://www.iamcal.com/publish/articles/php/parsing_email/.
