Freek Lijten's Blog: Currently on PHP's internals - Property Accessors
Freek Lijten has posted another "Currently on PHP's internals..." post to his blog today (here's the previous one) with a look at the discussions around the idea of having "property accessors" in PHP - a standardized way of defining getters/setters in objects.
Today I will be discussing a feature that at this moment is called "Property Accessor". It is a method of defining getters and setters. Originally an RFC was defined as early as september 2009, but recently new discussion took place and an actual patch was created. There is no certainty this feature will ever make a PHP version but discussion seems to target implementation details and not the feature itself, so things are looking bright for this feature.
There's two RFCs posted about the topic - the original proposal (from Dennis Robinson) and a patch for implementing them (from Clint Priest). The proposal replaces the common magic getters/setters (__get & __set) with the optional "get" and "set" keywords inside of custom-defined properties.
