I have a bug report for a user of my Google Wave
extension:

http://code.google.com/p/micke/source/browse/GoogleWave/GoogleWave.php (source)
It seems Parser.php sends the parser object to my function as a value($parser)
rather than as a reference (&$parser):
[Tue Oct 06 16:57:53 2009] [error] [client x.x.x.x.] PHP Warning:
Parameter 3 to waveRender() expected to be a reference, value given in
C:\\Apache2.2\\htdocs\\mediawiki\\includes\\parser\\Parser.php on line

Why is this? I don't get an error like this in any of my test installations
(although I have never tried it in a Windows environment). Googleing gives me
nothing...
My questions are these: Why does this happen? Is it something with the version
of PHP?
<snip>
PHP 4 and PHP 5 handle objects as function parameters differently.
Mediawiki now considers PHP 5.0 or later as a prerequisite (5.1 or
later recommended). The warning you quote is a plausible consequence
of using PHP 4 under certain circumstances, so that is the first thing
I would check.
