Class question

[jordanj]

ok.. So I am a little curious how effective the following code is. I know it works, but what are the pros/cons and other what not.

<?
class Foo {

function New_Object($obj = ""){
	if(class_exists($obj)){
		return new $obj;
	} else {
		return false;
	}
}

}

class Bar {

function Print_Hello(){
	echo "Hello";
}

}

$a = new Foo;
$b = $a->New_Object("Bar");

$b->Print_Hello();
?>

That code is fairly redundant.

All you're doing is using the Foo Class to instatiate an object, but because of PHP's garbage collection and memory handling.. there is no need to "take care of" your object references.

You might as well do this:

$a = new Bar;
$a->Print_Hello();

If you have many (20+) objects on a page, maybe you have a class that keeps a hold of all of them. I wouldn't recommend this... but I can see that as the only point of having a wrapper.
