You can define the functions for validations as per your requirements in a seperate php file,and include in various php files and use it.Hence it becomes a predefined function.For example consider below validation function,u can define it in a seperate file and use it in other php files where you need email vaidations.
$email = input($_POST["email"]);
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$emailErr = "Invalid format and please re-enter valid email";
}
