how fix an error Creating default object from empty value

Question

I've a script with variables in a class ($slug).

When I run this script, it works, but I get a warning: Warning: Creating default object from empty value. I know, I can hide this warnings in my php.ini, but how can ik fix this warning?

    $test = new myclass();
class myclass {
    private $order;

    public function __construct() {
        $this->order = (object) NULL;
    }
    public function setVars($slug, $number) {
        $this -> order -> $slug -> number = $number;
    }

    public function getVars($slug) {
        echo $this -> order -> $slug -> number;
    }
}
$test -> setVars($slug="hello", $number=5);
$test -> getVars($slug="hello");

1) You are instanciating the object before the class definition. 2) Modify your method default value to: function setVars($slug, $number=5); — rogeriolino, Sep 24 '13 at 12:24

Simply define order object as stdClass

public function __construct() {
    $this->order = new stdClass();
}

see this: Creating default object from empty value in PHP?

also this: http://www.php.net/manual/en/language.oop5.basic.php
