PHP Dynamic Function Variables?

Question

So in the base PHP Functions (probably not a good reference but anyway) example, the function array_push($arr, $info) - you can put as many items in the $info variable as you want, but example if you don't put in a paramater in a function that you made, example public function __connstruct($conn_string, $drivers), how would one want to achieve making the $drivers variable not needed unless the function is called with it.

Is it a special type of variable in the function?

default argument values?!

Try this: default arguments

public function __construct($conn_string, $drivers = null)
{
  // do something
}

This makes $drivers an optional function argument
