This isn't 1.3.23's fault. If you have installed the PHP bindings, and
have put it in the extension autoload list, then it will be loaded
before the script is executed. Running dl() on the .so will then cause
function redefined errors. Removing the .so from the PHP extensions
directory will cause a minor "couldn't load extension" warning, and
the tests pass - this was using 1.3.23 before your last commit, but
with the changes from mine.
We should probably run PHP with a blank config file when testing, so
it doesn't load any of its configured modules.
I also think I've discovered the problem with the Weight director. You
added private clone() which is pure virtual - it seems that SWIG is
generating the director (which is a subclass) without implementing
clone() (presumably because it's private), for the director is still
abstract. Other code requires it to be instantiatable as is.
SWIG probably needs fixing to implement private methods. A short-term
fix on our part might be to make clone() protected, which is slightly
icky, but should do the trick. Haven't had a chance to test this,

Probably. I've #ifndef SWIGPHP4 for the moment on the second
constructor (it's for Database, not Document, so it's not terribly
important as you can use auto() instead).
