Forgot how to use the scope in this form.

I've seen it somewhere where say you have a abstract sql database class, and you want to do something like below(doesn't work, forgot how to do it).

 

<?php
class test {
public function test(){ echo "test"; }
}
class test_type {
public $db;
function __construct()
{
	if( 1 == 1 )
	{
		$this->db = new test;
	}
}
}

$type = test_type::db;
$type->test();
?>

 

See in the constructor i want to like..check which type works best, say if i had mysqli or mysql i want it to auto detect and create a new class like i got above, how would that work, if you understand what I mean.
