They simply mean that return is used as a means for a function to give a value back to what called it, the actual value that is returned is whatever follows the return statement. So "return $something" would return whatever was stored within the "something" variable.

Let's say you wanted to make a function that added two numbers together and then gave you the answer, to do that you have to use return like this:

function sum($a, $b) {
    $c = $a + $b;
    return $c;

$result = sum(5, 10);
// $result now hold the value 15, as that is the result that the sum method returned.

You can pretty much think of it as doing the reverse of supplying an argument to a function. Instead of passing a value to the function, you are receiving a value from the function, which can then be used outside of it.

Wow its making more sense now so if I did some math in a php function and I wanted the answer to be revealed to me I will have to use the return code to get my answer? Like for example 1+2 and I want my answer then I will use the return code to give me this right = 3 ? I know that's not php example but i'm trying to make that math example easy for me to understand what your really trying to say in easier terms for me to understand.
