This is really quite simple to understand folks...
The guy has a class that is sitting there doing it's thing.
He has a function (say it's 'DestroyMe') that should do simply that.
The best case I can imagine...
The class is 'object' and it interfaces with a row in a table in a
database.
If you're going to delete the object's row from the table, it probably
makes sense to destroy the class handling it.
function destroy() { delete row; destruct class; }
Thus it would be helpful to be able to do what he's asking.
Now whether it fits within the realm of responsible coding or not I'm
not the judge... lol

It's tough to understand what your problem is without more code. If you
are doing:
for ($i = 0; $i < 1000000; $i++) {
$obj = new Foo();
// do stuff with $obj
unset($obj);
}
That should be sufficient. Could you be more specific?
Usually, if the PHP interpreter is running out of memory, you've got
some bad code that needs refactoring.

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!
