if (!preg_match("/^[A-Z0-9.%-]+@[A-Z0-9.%-]+.[A-Z]{2,4}$/", trim($_POST['email'])))
Using preg_match.
使用 preg_match。
Because ereg_* functions is deprecated in PHP >= 5.3
因为 ereg_* 函数在 PHP >= 5.3 中已弃用
Also for email validation better used filter_var
也用于电子邮件验证更好地使用filter_var
if (!filter_var(trim($_POST['email']), FILTER_VALIDATE_EMAIL))
echo 'Email is incorrect';
