Apparently, you don't have a function called session_is_registered.In the case that it is defined in another file in the same directory, then add this line in the top of the page

include("YourFileName.php");

I hope this helps.

@godslove

What PHP version are you using?

session_is_registered() - You can't used the same function, it only works once.

Try this:

<?php
session_start();
if (!session_is_registered(ulogin)) {
    header("Location: login.php");
    die();
}
?>

what error appears?

I tried using your codes by replacing header() with a basic echo statement, and it work fine.

If you are using PHP 5.4.0 then this function is no longer available.

[shhh]

@pritaeas - yes sir thank you ,im using that version, how can i replace it?

[shhh]

pritaeas -Thank you ~ i already figure out -instead of using session_is_registered , i used $_session.

[lps]

@godslove
suggest you to use isset($_session) to do it. As without isset(), it return false if the variable is set to 0.

[rotten69]

I previously thought you were defining a custom method. I'd go with the following code.

if(isset($_SESSION['username']) ){
    do something;
}
