Hmmm.... I agree about the reassigning of $this, but not the passing of
$this by ref.
Example:
Class A {
public $tableName = 'Forum';
public $childObject;
public function __construct() {
$this->childObject = new B($this);
}
}
Class B {
private $parent;
public function __construct(&$parent) {
$this->parent = &$parent;
}
public function get_stuff() {
// Generate SQL useing the parents global table name settings
etc....
}
}
