What if $name=Null ?

The code in the video is

<?php
function get_info($name, $title = Null){

  if($title){
    echo "$name has arrived. They are with us as a $title.";
  } else {
    echo "$name has arrived. They have no title.";
  }
}

get_info("Mike");
?>

What if instead we want the name to be null?

<?php
function get_info($name= Null, $title ){

  if($name){
    echo "$name has arrived. They are with us as a $title.";
  } else {
    echo "$name has arrived. They have no title.";
  }
}

get_info("Mike");
?>

What would we write in the parathesis? get_info();

If you have a list of parameters like in your example you need to supply them left-to-right to preserve the order.

get_info(null, "Mike");

Is how you'd skip the first parameter and send in the second.
