Question

If you have two classes extending the same base class, and need to make one of them override a function to take an additional parameter. Is it okay to always pass the additi

Answer 1

There are two ways to do this:

Extend the methods to use default parameters:

public function doSomething($input=null) {}

Note that you'll need to do this for all instances, even if it isn't used.

In this case, you may want to use the arguments array of the method:

public function doSomething() {
  $args = func_get_args();
  if (isset($args[0])) { $this->doSomethingElse();
}
