[RESOLVED] Question about new'ing objects

[ugasucks]

Can someone please explain what the difference between

$a = new Foo()

and

$a = &new Foo()

is. I understand how the reference operator works for a parameter to a function, but what's the difference here? Don't I still have the ability to change the object as I wish even if I don't use the & ?

Thanks!

In PHP5, nothing.

In PHP4 and below,

$a = new Foo();

Creates a new Foo object, then immediately copies it and puts that object into $a. Whereas if you use the &, it won't copy it.

In PHP5 objects are all references anyway (even if you don't assign them with &)
