php: new object from "ClassName" and array of args

Question

I have string containing classname and an array of args.
$classname($args) works, but in this case I have only 1 argument in constructor
Anyone know, how to do this with args expanded?

$reflection = new ReflectionClass($classname);
$object = $reflection->newInstanceArgs($args);

Before reflection, I had this exact same problem. Know what I did? Generated a string and eval'd it. Disgusting.

yes, I don't see another solution without reflection too. However, when using interfaces, the factory-pattern (or such), something like this is usually not required.

Haha I just asked this question: PHP passing a class as a reference?

And you can't expand the $args. You could try passing $args[0], $args[1] etc.
