Since you're using call_user_func_array() to call your internal methods
already (just to expose protected methods publicly?), you could add $DB as a
parameter.
public function __call($method, $args) {
array_unshift($args, $this->DB);
return call_user_func_array( array( $this, $method), $args);
}
protected function readSomething($DB) {
$DB->query(...);
$DB->numRows();
...
}
I would advise getting used to the $this-> everywhere. I can from Java where
that's not required but don't really mind it anymore. However, the above
would work and be automatic once you added the parameter to each method.
Peace,
