I'm struggling to narrow this down, and am chasing my tail to figure
this out. I apologise for the imprecise nature.

PHP: 4.3.2 (latest RHEL 3 version; php-4.3.2-19.ent.src.rpm)
OS: Linux kernel 2.4.21-15.0.3.EL
Distro: RHEL 3, all updates

I have an app that defines two global class instances, one for the
database connection, the other for handling user authentication. The
first is instantiated in uDatabase.php the other in uAuthenticate.php.

In building a page, there are several files that call require_once with
one or the other file, e.g.

require_once 'uAuthenticate.php';

Which creates an a global instance of a class defined in another file,
performs some checks, &c.

I'm using require_once with the understanding that once this file has
been included, that any subsequent require_once call to the same file
will be ignored.

My problem is that it appreas that in some cases require_once destroys
the instance, i.e. var_dump($Auth); or var_dump($Database) displays NULL.

I'm currently trying to determine rhyme or reason for the problem, but
haven't found any pattern. It comes and goes depending on which file
first calls require_once and the order, but makes no sense.

ANY ideas apreciated. :-)

Thanks,

James
