[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 [Select]

1. function countNumbers() {
2. echo ($x + $y);
3. }

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 [Select]

1. function countNumbers() {
2. $rtnval = $x + $y;
3.  
4. for ($i = 0; $i <= 5; $i++) {
5. return $rtnval;
6. }
7. }

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

Code: PHP [Select]

1. echo countNumbers();

or

Code: PHP [Select]

1. $numbers = countNumbers();
2. 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!
