Lazy loading of object variables in php using __get()
Aug 08, 2008 @ 14:22:51

Recently, Cormac posted this look at a method for lazy loading on variables in an object with the magic __get method.

I used the magic method __get() to load the images into the [Product] object when they were needed. __get() is called whenever something tries to access a variable that is not set or publically accessible, so basically I used that to load the images whenever some other piece of code tried to access Product::images.

He includes a quick bit of code that fires off an internal private method for the class that loads up the images. In his example, if they're already loaded, it never gets called.
