So we are "regexing" emails again? #OUT OF coding_php_validation.php COPY case 'email': { $expression = "/^([a-z0-9_\-\.]+)@([a-z0-9_\-\.]+)\.([a-z]{2,5})$/i"; $errorText = "The email does not appear to be a valid type."; break; } #END COPY What should be valid email addresses according to RFC 2822 [1]: !#$%&*+-/=?^_`{|}~@example.com "@"@example.com Not valid email addresses: "\"@example.com @@example.com - -@example.com Valid email addresses according to the Multipurpose Internet Mail Extension (MIME) [2]: ä@example.com Ã(c)@℞.com
