In PHP 5 can I instantiate a class dynamically?

Question

For example is something like this possible in PHP?

class foo
{
    public $something;
}

$class_name = "foo";

$f = new $class_name;

Answer 1

Yes, works fine.

Was it really easier to ask this here than to just test it?

Answer 2

That should work, yes.

You can also do:

$f = new $class($arg1,$arg2);

Answer 3

Yes of course you can instantiate using dynamic names;
