error due to function definition

I want to call a function if it has been defined and not call it if it
hasn't. I am using this code:

if (function_exists(editForm())) { editForm(); }

I also tired:

if (editForm()) { editForm(); }

When I first implement this conditional in this script, the function
has not yet been defined. Later, when the script is run again after a
post submit, the function gets defined and the conditional then
results in the function being called.

When I run this on my local machine using PHP Version 5.2.2 both of
these scripts run fine, doing nothing when it is not defined and
calling it when it is. It shows no errors.

When I upload this to my web server which is using php 5.2.5, and run
this script I get the following error:

"Fatal error: Call to undefined function editform()"

when it gets to this conditional. Can anyone tell me what is going on
here. Has something changed between php 5.2.2 and 5.2.5?

I have searched everywhere and not been able to find any explanation
for my problem.

How do I accomplish this procedure?

Thanks,

The manual says the function name should be a string, and indicates the
brackets aren't required.
Ie
if (function_exists('editForm')) { editForm(); }

I imagine this should cause a problem, as it will try to call the function
in the evaluation, and if it isn't defined flip out. If the function
returns a boolean then the matter is further complicated.

Thanks -- Worked perfect. Now I remember reading something about that
once.
