When is a class too long? [closed]

Answer 1

No more than 17 lines. No more, no less. So if is under 17 lines carriage returns will do the trick. If its more than 17 you will need to start calling other functions from within the function.

For example:

public function myFunction() {
...
line 17: myFunctionPart2();
}

public function myFunctionPart2() {
...
line 17: myFunctionPart3();
}

And so on.

Its pretty standard programming practice.
