It appears that the class would only ever be a single instance.
If so you should be setting the values within the constructor.
ie;
$test = new WachtwoordGenerator(8, 3, 2, 4);
Although this appears to be a test and learning project it's a good time to
create some good habits.
The class should encapsulate more functionality than this one does.
The numbers "8, 3, 2, 4" have to come from somewhere. Why not generate them
within the class itself with rand numbers.
Then you could do the following;
$test= new WachtwoordGenerator();
$password = $test->pword();
Now you only have two statements involved in generating a password.
A very big part of "oop", or "obp" is data encapsulation.
There was once a time when you had to oil bits of an internal combustion
engine every time you used it. Today every such engine I know of uses
encapsulation to do the oiling for you. You just need to keep an eye on the
oil available to the system. No, I'm not calling you a "dipstick" :)
You are oiling the engine yourself when you call "_set" on a class that is
created once for it's output then discarded.
No crticism inteded here, just a nudge toward a better understanding of the
use, and usefullness, of classes.
