PHP Version: 5.1.2
New Comment:
The problem comes into mind when your creating an object and going
through a loop. The script just grows and grows until your out of
memory.
We are creating an object doing what we need to do with it and trying
to destroy it. Anybody have a solution?
I really don't want to have to go through every variable inside the
object and do an unset().

It's absurd (well, maybe not absurd, but not needed) as long as PHP has
destructor methods.

Scott, do you really think that
$object->im_done_please_kill_me() is an absurd idea?

In php5 no php variable actualy contains the object instances, they
contains pointers to instances. Thats why unseting the $this variable
does nothing. Just because you stop knowing where it is doesn't mean it
ceases to exist.
And the $this variable is a special case. It would not make sence to
unset it.
As far as I can understand, $this shouldn't even affect the garbage
collection, if it did(and php doesn't adjust for recurive pointers) the
garbage collection would never destroy objects instances!

class FalseClass
{
public function __destruct()
{
echo "Gonna die, man";
}
}
$f = new FalseClass;
unset($f);
RESULTS:
Gonna die, man

Thanks Scott, that makes sense.
Does that mean there is no way to accomplish this in PHP5? I guess so.
I'd like to see this added to the docs.
