Re: Re: bug of the day: $this

Why do the (cheap) checks implemented in debug_backtrace not work for this? George On Friday, December 6, 2002, at 04:11 PM, Stig S. Bakken wrote:

It won't be different in ZE2. This is not a bug though, but a tricky design issue. The problem is figuring out at runtime when to set $this or not in a method. What most people would probably find intuitive, is that $this was set only in methods called in the object, but this would require pretty expensive checks for every method call. Andi can shed more light on this if needed. - Stig On Wed, 2002-12-04 at 00:25, Markus Fischer wrote:

Hi, $this stays defined when an instantatiated member function calls a non-instantiated member function.

Correct. I actually find it quite interesting. :) It can be useful at times, I have used it in my libraries as a feature. There is an interesting article on the subject: http://www.advogato.org/article/470.html
