Wikimedia Bugzilla is closed!

I obtain the latest ConfirmEdit like so:

svn co http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/ConfirmEdit/
A    ConfirmEdit/MathCaptcha.php
A    ConfirmEdit/ConfirmEdit.i18n.php
A    ConfirmEdit/FancyCaptcha.i18n.php
A    ConfirmEdit/ConfirmEdit.php
A    ConfirmEdit/FancyCaptcha.php
A    ConfirmEdit/captcha.py
A    ConfirmEdit/MathCaptcha
Checked out revision 22664.

I make no customizations.

I make the appropriate change in LocalSettings.php:

require_once( "{$IP}/extensions/ConfirmEdit/ConfirmEdit.php" );

I point Firefox 2.0.0.4 to the wiki's main page and get the following error message:

Parse error: syntax error, unexpected T_BOOLEAN_AND, expecting '(' in /home/.petula/multiverse/public_html/wiki/extensions/ConfirmEdit/ConfirmEdit.php on line 320

With my limited knowledge of PHP, I toyed around with parens to no avail.  I conducted extensive research to try to resolve this myself.  It seems MediaWiki has changed something underneath this extension.  I have not tried to see if this extension works on earlier versions of MediaWiki.
