PHP alternative to session_is_registered

Question

Hi all, does anyone knows the alternative to the deprecated function session_is_registered in PHP5?

here's my code:

ob_start();

session_start();

if(!session_is_registered(myusername))

{

    header("location:main_login.php");

}

ob_flush();

Thanks,

Mauro

Answer 1

"You need to set and reference $_SESSION variables only." For example:

if( isset($_SESSION[$myusername]) )

From http://www.phpfreaks.com/forums/index.php?topic=263189.0

Answer 2

on a side note, best use $_SESSION['username'] = $myusername;. Using the $_SESSION[$myusername] as a variable may overwrite existing variables in the session.

Answer 3

Use session_id()

if (!session_id()) {
 // do stuff
}

if there is no session id nothing will be returned. (docs - session_id() )
