[RESOLVED] $GLOBALS doesn't work!!

[thepeccavi]

Here is what I am doing:

index.php:

<?php
require('config.php');
echo head($title);
echo body($content);
?>

config.php:

<?php
// *DB login*
// *Fetch settings*

$GLOBALS[sitename] = $fromDB;
$GLOBALS[slogan] = $fromDB;
// *etc.*
include('html.php');
?>

html.php

<?php
function head($title) {
// *Code that needs to use stuff from $GLOBALS*
}
function body($content) {
// *Code that needs to use stuff from $GLOBALS*
}
?>

My problem is that the $GLOBALS don't seem to be accessible in html.php. I have tried adding "echo $GLOBALS[sitename];" to index.php, but they don't seem to be set there either. Even if I put that line into config.php it doesn't work!!

The "$GLOBALS[x] = $y;" lines are inside a while loop, but not a function.

Why aren't the $GLOBALS being set?

PS. I think I have quite an extensive knowledge of PHP except for variable scope and (especially) classes (hint, hint!).

PPS. I haven't posted on PHPBuilder for ages so my explaining skills may have deteriorated (I used to post so often that I got quite good!) - please let me know if I am not being very clear!

You don't show us how you (attempt) to use the global variables inside the functions, which is presumably the bit that's not working.

But....

Variables declared outside a function are referenced inside the function using the $GLOBALS array. You seem to be doing it the other way around. (See Example 2 on the page describing the [man]global[/man] keyword for use of the $GLOBALS array; the global keyword itself is illustrated in Example 1.)

Oh, and if that is how you're writing those array indices, you might want to look at this section on array do's and don't's.[/bar].

I feel incredibly stupid.

The variables were never set because I have an if clause that was broken DOH!!!!!!!!!!!!!!

Sorry.

I now know how to correctly use the $GLOBALS array - thanks Weedpacket!
