I had an issue with arrays and copying them by reference as follows.

	// Loop on the list and insert default values
	foreach ($navigation as &$item)
	{		
		$children = &$item['children']};

		foreach ($children as &$child)
		{
		 // Do stuff
		}
	}

This would give me error message 

Fatal error: Cannot create references to/from string offsets nor overloaded objects in /var/www/dev/kh_system/navigation.php on line 103

Even though $item['children'] is an array.

The workaround is to do a for ($i =0;$i < count($Item);$i++) and to then access the children like this

$navigation[$i]['children']
