calling functions with include

suppose i have...

<?php
include("common_functions.php");
fxn1();
fxn2();
?>

i want fxn1 and fxn2 to be on the common_functions.php page, but every time
i do that i get a Fatal Error: Call to undefined function: fxn1() in
/home/paradox/public_html/index.php
I'm guessing i would get an error for fxn2 but since it's a fatal error
the code never gets executed far enough to see if it happens.

does it make a difference if i put a space after the one aka fxn1 () or
fxn1() or are they same? I've seen them written differently on different
sites.

if i call fxn1() and fxn2() directly from common_functions.php it works
beautifully, it's only when i try calling it from index.php using the
include feature

i've used "include" and "require_once" but i thought by doing it would
basically cut and paste all the code from common_function.php into the
index.php so that i could just call the function with no worries.

Check if the common_functions.php file resides in the same directory as the
script that includes it and that this script is called/included from the
same directory.

Below is a situation which could cause an error:

Directory structure:

../index.php (file in root dir, accessed by the browser)
../files/include.php (includes common_functions.php)
../files/common_functions.php

When index.php includes the include.php file, the include call to
common_functions.php in include.php should have the same path as index.php
uses to include include.php:

index.php:

<? include "files/include.php" ?>

include.php:

<? include "files/common_functions.php" ?>

Another way to test this is to use require instead of include. The require
construct throws a fatal error, where include only throws a warning, which
is probably surpressed in your configuration.
