PHP Function Arguments.

Hello, why would I need to pass an argument when calling the function? (see below):

function get_name($name) {
  echo "Hello, $name";
}
get_name("Alex");

Thanks!

Hi Alex, Is there any way you could be more specific about your the question? From the looks of things, the reason an argument is necessary so that the echo statement can echo the supplied argument. Is there something else that is confusing you? :)

Because in the function definition there is a required argument. You can make it optional by doing

function get_name($name = "default") {
  echo "Hello, $name";
}
