PHP OOP Tutorial 1: an introduction to Object Oriented Programming

This is a basic introduction to Object Oriented programming.
Here, I introduce classes, public and private variables and methods, magic methods, and method chaining.
I use a diagram to show the concept visually before creating the code, and then I test it in the terminal.
I also show variable casting to ensure that information is properly handled, even when it is of the wrong type.

As always, I will post on my site, kloplop321.com/php-tutorials/ with the source code and any resources I use. Please make sure to subscribe if you like my tutorials, and feel free to share them with others.

@polydactylstrangle I think you are right. It should be ($this->z). $f is not defined in the Some class.

Hi, i really love your tutorial, no nonsense, i was just slightly confused as to why you put into the foo function return new Other($this->a,$this->f), shouldnt that be return new Other($this->a,$this->z),it only works for me this way anyway but you are definitely waaay more intelligent than me so im taking what you say as gospel.
