Change in the way get_object_vars behaves in PHP 5.4 and PHP 5.5

get_object_vars.php

<?php

abstract class AbstractModel {
    public function toArray($includeProtected = false)
    {
        if ($includeProtected == true) {
            return get_object_vars($this);
        }
        // Wrapping this object in a closure changes the lexical scope, which
        // allows us to easily return only public properties.
        $self = (array) $this;
        $clean = array ();
        foreach ($self as $key => $value) {
            if (strstr($key, '*')) continue;
            $clean[$key] = $value;
        }
        return $clean;
    }
}

    protected $a = "t";
    public $b = "c";

var_dump($m->toArray(true));
var_dump($m->toArray());
