Global variables, so functions can access them!

[Hyaku_]

Hi!
How can I define a variable, so that it can be accessed from a function? For example:

first_page.php
[code]$global_variable = 10;
include('funct.php');[/code]

funct.php:
[code]function echo_global_variable(){
echo $global_variable;
}[/code]

Thanks!

[code]
<?php
$myname = "Jamie";

function MyFunction(){
global $myname;
echo $myname;
}
MyFunction();

//You just need to add global before the variable
?>
[/code]
