9,938 PointsWhat 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();

9,385 PointsIf 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.
