[PHP] Confused with functions

[RedPillow]

This has nothing to do with the thread I made few minutes ago.

Anyways ... I need help with these thing related to PHP-functions:

- How do I set what the function needs to work?

Like ...

Code: (php)

function countNumbers() {
echo ($x + $y);
}

Now, how do I declare, that the function I made needs parameters $x and $y to count like so:
countNumber(1, 2);


Second question is, can function return multiple values, like with a loop?

Code: (php)

function countNumbers() {
$rtnval = $x + $y;

for ($i = 0; $i <= 5; $i++) {
return $rtnval;
}
}

Third is, can I use function directly to output something like so:

Code: (php)

echo countNumbers();

or

Code: (php)

$numbers = countNumbers();
echo Numbers;

RedPillow, although you can get answers to your questions -- i think you would find that getting a book (free ebook or normal book) on php would be extremely helpful to you -- in very important ways.  I urge you to find one, it will be worth the effort to read it.

Yeah ... there's sometimes just too much questions I need answer for.
I'll go check the nearest library!
