Is there any point to unset($this) in destructor?

Question

I came across one class and what cought my attention right away was this:

public function __destruct() {
        unset($this);
    }

My first thought was that this is just plain stupidity, it fact it looked so idiotic that I thought that either there really is a good reason to do this or the author is just clueless

Any thoughts? Any reasons to do this?

Answer 2

My first thought was that this is just plain stupidity, it fact it looked so idiotic that I thought that either there really is a good reason to do this or the author is just clueless.

The latter, I'm afraid: there is no point in unsetting an instance on destruct. It might be the original programmer is a big fan of being explicit, but the worst thing is that this doesn't even work:

<?php
class Foo {
    function __destruct( ) {
        unset( $this );
    }
}

$foo = new Foo;
$foo->__destruct( );
var_dump( $foo );
