Answer 1

the goal of functions is shorter code and less effort and less time 😎

Answer 2

A function is a block of statements that can be used repeatedly in a program.
so if you want to get the sum of 2 numbers more the one time in a program For Example :
You Need To get the value of num1 and num2 and get their sum :
$result = $num1 + $num2;
$echo($result);
and instead of writing these lines of code more than one time you can use functions example:
function sum($num1,$num2) {
$result = $num1 + $num2;
return $result;
}
so any time you want to use this block of code you just need to call it by name for example we want to get the sum of 2 and 3 after we define the function we just nee to write:
sum(2,3);
and this will do all the work for you 😃
