usage of 'global'... when does it work!?

[nielskg]

Hi,

I have made a header.php and a footer.php which I include at the beginning and at the end of a larger index.php.

Between these header.php and footer.php there are several other include functions and some self made functions. The problem is that a variable from the header.php is disappeared when echo'd at the footer.php.

Is there a trick to use a special 'global' option to make it usable in the whole index.php file? (That is in every 'require', 'function' and 'include'?)...

Thanks,
Niels

ya, globals are the best
try this on for size:

<?
class worldObject {
var $name = "No Name";

function belch() {
echo "braaaaaaaaaaaaaap!!!<br>\n";
}

function drink() {
echo "mmmmmmm beeeeeeer!<br>\n";
}

} // end Class

$GLOBALS['fred'] = new worldObject;
$GLOBALS['fred']->name = "Fred";

echo "Hi, I'm ". $GLOBALS['fred']->name."<BR>";

function doSomething() {
$GLOBALS['fred']->burb();
}

doSomething();

function doSomethingElse() {
$GLOBALS['fred']->drink();
}

doSomethingElse();

$GLOBALS['fred']->name = "Barney";

echo "Hi, I'm ". $GLOBALS['fred']->name."<BR>";
?>

And there you have a Global object that you can do whatever you want with from anywhere in your scripts.

A handy thing to check out sometime is:
<?
print_r($GLOBALS);
?>
...will dump the GLOBALS[] to the page.
