function calling another function

[jesus_hairdo]

I've got 2 functions in 1 included file. I want 1 of the functions to call the other, can i do this straight off, or do i need to include the file in itself?
Also if i set variables out side a function in the include file can all of the functions access these variables.
ie.

<?
$var = var
$var2 = var

function dosomething()
{
print $var
print $var2
}
?>

The first thing the PHP engine does BEFORE it exeutes any code is include any include files - so bearing that in mind any code in the include file should be treat as if it is part of the main code.

So the answer is the file only needs to be included once and all variables are avaliable to the functions as long as you tell the function that the variable was declared outside using the 'global' keyword. eg:

---

<?php
$var = "hi there";

function dosomething()
{
global $var;
print $var;
}

?>
