Tobias Schlitt's Blog:
Reflecting private properties
February 15, 2008 @ 12:02:00

Tobias Schlitt has posted a handy tip about using the Reflection API in PHP5 - specifically its accessing of private properties in a class.

I recently stumbled over reflecting private properties in PHP again. As you might know, this was not possible until now and if you tried this [code] PHP thanked it to you with this [error that is cannot access a non-public member].

He notes that, while the behaviour is correct, it still makes things like metaprogramming impossible. So, what's a developer to do? Patch it of course! Tobias and Derick Rethans persuaded two other developers (Derick and Marcus Borger) to include a patch that allows the Reflection API to see these private variables.

To make it work, you have to use the setAccessible method on the Reflection object to set which of the properties you want to be able to get at.
