php functions within functions?

The other page must be included (or required) before it's functions are called. The variables must also be declared global in both functions.. e.g.


// page1.php

<?php

require_once("page2.php");

firstFunction();

function firstFunction() {
global $x, $y;
secondFunction();
echo $x . ", " . $y;
}

?>

// page2.php

<?php

function secondFunction() {
global $x, $y;
$x = 5;
$y = 10;
}

?>

Good luck!
 
So i have one php script that is mostly one function... in this function it requires another script and calls functions from it. Now I cannot get the first script to see variables made by the required functions even with global. So is there a way to have a function, call a function from another script and allow the first script to use the variables the second produces?

thanks
