a class question

Anon

alright, so i have all my classes in a file that i include into my script. then i use my script to figure out all the stuff that needs figuring on the page. but i have a small problem that i can't seem to find an answer to.

i make an object and then start using functions and such to find page variables. but i can't use my objects functions inside my script functions. any way around this? here is a short example:

include "/blah/base.class";

$page = new misc($blah, $blah);

function func1();
{
$id = $page->findID();
return $id;
}

$id = func1();

now, that's just a quick sample. i don't have just pointless functions like this. i tried passing $page into the function but that didn't work. any help?

thanks in advance.

This is a scoping problem. inside your function, PHP can't see $page.

There are 2 solutions I see.

1:
function func1() {
global $page;

Not my favorite. I hate Globals for personal reasons. professionally, I just detest them because if you are trying to write good OO code, they break a lot of rules.

2:
function func1($page) {
This is the most common way to do it and is probably the best. mainly because a function should either have everything it needs to operate or have everything passed in.

A 3rd option would be to restructure your objects. Without more information thought, I can't make any recommendations on this.

okay, so i have tried passing it into the function, but i get an error message:

Fatal error: Call to a member function on a non-object in /var/www/html/chrisroberts/index.phtml on line 29

i have it passed like this:

$page = new misc($blah, $blah)

function func1($page)
{
$id = $page->findID();
return $id;
}

$id = func1($page);

is there any reason why this shouldn't work?
