it works here.
try to do a var_dump($groups); and watch it closely. (btw you shouldn't
do 'echo var_dump'..)

Description:
------------
I'm having a preg_match function fail periodically. I finally found a
specific input string that fails in PHP but works fine in Perl. I'm at a
loss why.
Reproduce code:
---------------
$pattern = "/(\w\w\w) (\d+) (\d\d\d\d) (\d+):(\d\d)(\w)M/";
$input = "Dec 17 2008 2:23PM";
$rv = preg_match($pattern, $input, $groups);
echo var_dump($rv);
Expected result:
----------------
A non-zero result indicating the pattern matched.
Actual result:
--------------
Zero.
