Hey,

This might seem really noobish, but I wanted to create a simple, but effective email validation function.

Most other functions/classes were too complicated: they did things which I did not need and were way above me. My aim was to make sure that the email a user entered basically was an email.

I would love suggestions on how I could improve it, as I am sure there are improvements to be made!

PHP Code:


			
function checkEmail($email) {
    if(eregi("^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$", $email)) {
        return true;
          }else{
        return false;
        }
}

uses as such:

PHP Code:


			
$email = "gwp123@gwp123.com";

    if (checkEmail($email)){
         echo 'its valid!';         
     } else {
        echo 'its not valid :(';
    }

This would echo out "its valid!".
