[PHP] Object type determined at runtime

2009-07-06 Thread James Colannino
Hey everyone.  I have a question.  Hopefully it's clear, because I'm not
sure quite how to ask it.  Basically, I have a variety of different
objects that a variable can be instantiated as in the same block of
code, its type being determined at runtime.  I want to be able to do
something like this:

$object = new $objType();

Where $objType is the type of object, which must be determined at
runtime.  I'm sure the syntax I have above is incorrect.  My question
is, is there any way that I can determine the object's type at runtime
and do the same type of thing?

Thanks!

James

No, you pretty much got it right:

class A{
public function e() {
echo Hello World;
}
}

$A = 'A';

$a = new $A();

$a-e();

 is, is there any way that I can determine the object's type at runtime
 and do the same type of thing?

You're asking a different thing there, but I'll throw it in for completeness:

(BTW, there's a distinction between classes and objects (random link:
