Having problems with include things and functions

This works in my friend machine but not for me :
My machine :
Ubuntu 6.06.1
Apache2 2.0.55
php5 5.1.2
mysql 5.0.22

The error is
Fatal error: Cannot redeclare tohtml() (previously declared in /home/chop/Web/Website/include/common.php:21) in /home/chop/Web/Website/include/common.php on line 23

[hitman6003]

Make sure that you only have the function "tohtml" once in your code.  The error means that you are trying to declare, or create, the same function twice.

Hi, i already know what the problem is, just dont know how to fix it, actually how to trace it down.

I think i did have
[code]
if (defined('_COMMON_INC') ) return ;
define ('_COMMON_INC', 1);
[/code]

so if the thing is included twice then nothing happends.

Thanks for answering.

I think it is more likely that you have include('common.php'); in more than one place - like it is included in a file which is included in common.php - what ever has happened ther is a second include of this file.

One of the reasosn why require_once is what you shoudl really use for a site wide script liek this.
