How do I make a function parameter optional?

Give it a default value in the definition

function I_am_a_function($first, $second = true){
    // things
}

if no value is given for the second parameter, the code inside the function will see it as true.

I assume I can set = null

yay... you can

I think you can set = pretty much anything.
