I recently scripted a web form in PHP and, of course, included some form validation. One of the things I did was check the email to see if it included the "@" sign. However, the only way I could figure out how to do it was to use "strstr($_POST['email'],"@")," and see if it returns anything. If the return is FALSE, I know that they didn't include an @ sign. It works just peachy, but is there a better way to do this?
