Declare the variable outside of scope of b and a (if you don't want to
use $_GLOBALS directly).
<?php
if (!$argc) ob_start('nl2br'); // trick to get stuff to print nicely
on either web/cli output
$thing = 1;
function a() {
global $thing;
b(2);
}
function b($newThing) {
global $thing;
$thing = $newThing;
}
echo "$thing\n";
a();
echo "$thing\n";
b(10);
echo "$thing\n";
?>
In OO style there is no 'friend' in PHP, which is a good thing.
