please help with email validation, preg_match

Hi guys

I need the best available preg_match regular expression to validate email addresses.
The expressions I've found failed with one of the following emails:


>
someemail/r@somedomain.com

etc.

Thanks!

 

Why not just use the filter function
http://uk2.php.net/manual/en/filter.examples.validation.php
also, e-mail addresses shouldn't have /r in them

 

Give filter_var() a shot:

function is_email( $email )
{
    return FALSE !== filter_var( $email, FILTER_VALIDATE_EMAIL );
}

PHP:

Of your three examples, the first two are invalid, but the third is valid, as forward slashes are allowed in the local portion.
