session - PHP alternative to session_is_registered

Question

asked Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

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

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

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