<?PHP
class Session{

    private static $instance;

    function __construct() 
    {
        session_start();
        echo 'Session object created<BR><BR>';
    }

    public static function getInstance()
    {
        if (!self::$instance) {
            self::$instance = new Session();
        }
        return self::$instance;
    }
}

Try that. You had an extra bracket.

The error was actually in the line function __construct(). It created a function and then an empty set of brackets (doesn’t actually error).

Then, you never ended up breaking out of the construct function so it error-ed when you tried to use the public parameter inside a function, which is not valid syntax.

This is why we make consistent bracket placement, so we always put stuff in the same place, and thus can easily spot mis-placements.
