Subject: PHP 5.0.3 losing $this
From: yml@dtlink.com (Yermo Lamers)


PHP 5.0.3 is losing $this. PHP 4.3.10 and 5.0.0 seem to work fine.

The bug originally appeared in 5.0.2.

I have submitted a bug report at:

   http://bugs.php.net/31525

I've not had alot of luck with reporting bugs through the bug tracker;
For instance see

   http://bugs.php.net/31508

where the guy claims PHP can't do recursion without crashing ... Ummm?

So I thought I'd try to ask here.

Unfortunately I've been unable to reproduce the 5.0.3 bug in just a few 
lines. I do have a script that's in my mind pretty short and the meat of 
it is only 8 lines long but it includes three classes needed to set up 
the experiment.

More information is available at:

   http://www.formvista.com/index.html?article_id=4

Direct link to the code:

   http://www.formvista.com/uploaded_files/php5_drops_object.php.txt

Scroll to the bottom.

The code has three classes:

   fv_basecomponent is a child of fv_basewidget is a child of fv_tree.

fv_baseComponent overrides a method in fv_basewidget called 
&getParentControl(). fv_baseComponent::getParentControl() returns a 
reference to $this.

In PHP 5.0.3 the reference returned is not an object and a nasty error 
is generated. I've tested this using today's snapshot
(php5-STABLE-200503051730).

It continues to work like a champ in PHP 4.3.10 and every previous 
version and like I said it used to work in 5.0.0.

Any help in tracking this down or devising a workaround would be greatly 
appreciated.

And if anyone has any thoughts on bug http://bugs.php.net/31508 that 
would be greatly appreciated as well; it's not quite the showstopper 
than the 5.0.3 bug is, but is causing me serious headaches as well.

Thanks

-- Yermo
