VG Tech: Comparing Your Privates in PHP

In a new post to their blog, the VG Tech folks talk about "comparing your privates" with a "hidden" feature of PHP. Don't worry, they're referring to private class properties on object instances here...

I was going to compare several private properties between to objects and started making a piece of code to perform the actual comparison using getters for the properties. I felt the approach sucked, and started looking into alternatives way to do this.

He shares what the current PHP documentation shares about comparing objects, but neither of them take private properties into account. He remembers, however, that object visibility is at the class level not instance level, allowing two object instances of the same class to have access to all properties of the other, regardless of exposure level. He includes a code snippet showing how to use this to compare those private properties.
