php

Question

<?php
$name = 'David';
function getName() {
global $name;
echo $name;
}
getName();
?>

// why would you use so many commands to generate one name

Answer 1

You could just use echo ‘David’; inside the php tags to get the same results

Answer 2

if you don't use function insside php then you can print using echo "David",
but here you have used function() so inside function you need global to get $name from outside the function then print echo $name
and getName(); runs the function outside the function
