simple require_once / config / functions problem

i would like my program to have a config.php with passwords and other
stuff.

i would like to have a functions.php to hold all my functions.

i would like the functions.php to include/require the config.php as it
will need it for database stuff.

i cant seem to get the functions in my functions.php to see the
variables in config.php


when i run the following on my machine i just get notices about the
undefined variables. what is wrong with this?

thanks for any help!!


here is the basic layout:

index.php:
<?php
require_once "functions.php";
myfunction();
?>

functions.php:
<?php
require_once "config.php";

function myfunction()
{
print("user: $user , server: $server , pass: $pass ");
}
?>

config.php:
<?php
$user = "root";
$server = "localhost";
$pass = "pass";
?>

You're using the variables defined in config.php _inside_ the function.
That turns them out of scope.
see http://www.php.net/manual/en/languag...bles.scope.php

Either declare them global within the function, or (better, I think)
make them constants in config.php



declaring the variables global:
<?php // functions.php
function my_function() {
global $user, $server, $pass;
print("user: $user , server: $server , pass: $pass ");
}
?>

making them constants:
<?php // config.php
declare('USER', 'root');
declare('SERVER', 'localhost');
declare('PASS', 'pass');
?>

<?php // functions.php
function my_function() {
echo 'user: ', USER, ' , server: ', SERVER, ' , pass: ', PASS, ' ';
}
?>
