Function session_is_registered is deprecated PHP
Installing an Open Source PHP system (on Php 5.3) I got the error:
Deprecated: Function session_is_registered() is deprecated in (filename).
I've solved this by using the functions
[code:xml]
session_start();
$_SESSION["variable_something"] = 'Yay! i'm into a session var!!';
en om te checken of deze bestaat:
if(isset($_SESSION["variable_something"])){
echo "Session is alive!";
}
