Derick Rethans, een van de core PHP ontwikkelaars en ook de ontwikkelaar van XDebug heeft zijn jaarlijkse "PHP Lookback" voor 2006 weer geschreven. PHP Lookback 2006 geeft een interessant overzicht van wat er nu allemaal is gebeurd binnen de PHP developers community en daarmee bedoel ik de ontwikkelaars van PHP zelf.

Anderen hebben inmiddels zijn idee overgenomen maar ze zijn nooit zo compleet als die van Derick :).

Andrew Yochum started the year with a thread on whether we should add a new magic method, "__iscallable", as a hint to the engine whether a specific method can be called trough the "__call" mechanism. Although I think this is a good idea, the discussion unfortunately turned to suggest throwing an exception later in the "__call()" method whenever a method could not be "called" through the "__call()" mechanism.

There were two different threads about how variables are destroyed when dealing with circular references. At the moment, PHP's memory manager will not free this type of variable as it does not know which one to free first—it's the traditional egg-and-chicken problem. In somewhat larger applications (or unit test suites—hint hint), this can cause a problem as memory is not adequately freed. Solving this is unfortunately a major task, and I hope that in the next year we can have a good look at possible solutions for this issue.

Kortom, een uitgebreidde blik in de PHP developers wereld: Derick's PHP Lookback 2006
