note 101693 added to filter.filters.validate

FILTER_VALIDATE_EMAIL does NOT allow incomplete e-mail addresses to be validated as mentioned by Tomas. Using the following code: <?php $email = "clifton@some"; //Note the .com missing echo "PHP Version: ".phpversion().'<br>'; if(filter_var($email, FILTER_VALIDATE_EMAIL)){ echo $email.'<br>'; var_dump(filter_var($email, FILTER_VALIDATE_EMAIL)); }else{ var_dump(filter_var($email, FILTER_VALIDATE_EMAIL)); } ?> Returns: PHP Version: 5.2.14 //On MY server, may be different depending on which version you have installed. bool(false) While the following code: <?php $email = "clifton@some.com"; //Note the .com added echo "PHP Version: ".phpversion().'<br>'; if(filter_var($email, FILTER_VALIDATE_EMAIL)){ echo $email.'<br>'; var_dump(filter_var($email, FILTER_VALIDATE_EMAIL)); }else{ var_dump(filter_var($email, FILTER_VALIDATE_EMAIL)); } ?> Returns: PHP Version: 5.2.14 //On MY server, may be different depending on which version you have installed. clifton@some.com string(16) "clifton@some.com" This feature is only available for PHP Versions (PHP 5 >= 5.2.0) according to documentation. So make sure your version is correct.
