According to the PHP Manual: Overloading, the magic method __get()
is for overloading properties, while __call()
is for methods. Since you are working with methods, you should use the one appropriate for its designed use. So for Readability, __call()
gets my vote.
As far as Security, I think any overloading is just about as equally secure, which is to say not really much at all, since it's about creating properties and methods that haven't been explicitly declared.
I haven't tested the Performance aspect of it. I would think the method __call()
would be better as it was designed for use with methods, but you may want to microtime(true)
a couple tests to see if it matters.
I honestly don't use __call()
since I haven't had the need to overload methods in my apps, or otherwise should say that I always declare methods in my object classes.
