it looks like this problem only happens when the script is called with php as an apache module, because true/false constants are not defined and appear as string which means they always evaluate to true !

but when you var_dump(true) or var_dump(false) on a command line call to php, then they are well defined as booleans !!!

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
