Cannot redclare class...

Fatal error: Cannot redeclare class dbstuff in /home/crnorth/dbutil/mysql.php on line 3

I've been using this code for several years on PHP 4 hosts and now I'm getting this
on a PHP5 host.

This class is used in several different scripts on my site.

How do I fix this? What do I need to check for?

I don't know of any reason why changing from PHP4 to PHP5 should affect this. Assuming your class definitions are in separate files that get included into your script, be sure to use require_once() rather than just require() to load those class files, so that you don't run into such a collision if your script or one of its include files tries to include a class definition file that has already been loaded. If that is not the cause of the error, then the only other possibility is that at some point you are trying to define a class when there is already a class by that name. Since I'm pretty sure "dbstuff" is not a built-in PHP class, it would have to be a class name duplication somewhere in your script and its included files.

Both scripts had this in it:
include("/home/crnorth/dbutil/mysql.php");
include("/home/crnorth/dbutil/dbconnect.inc");

Now, if I use require_once it should work?
I got it to work by commenting out both those lines in one of the scripts.

probably 'dbconnect.inc' has got a line
include('mysql.php')
... and this is what it should have

Your job is see to that 'mysql.php' is not included 2 times
so if using BOTH your lines in other pages, means that you get 'mysql.php' 2 times

Remove the direct include of 'mysql.php' in all pages, but the 'dbconnect'.
And try using only this in pages with any dbconnection:
include_once("/home/crnorth/dbutil/dbconnect.inc");
because you may have stuff in 'dbconnect.inc' that is needed for 'mysql.php'

require_once("/home/crnorth/dbutil/dbconnect.inc");
may be even better to use.
The script wont go on running, if not found file.

By the way,
it is better to use one of these names for that .inc file:
dbconnect.inc.php
dbconnect.php

.inc is often defined by servers as any text file, and not as a PHP file
