Yes, I know.

The environment, in which the webserver is running, is different from the environment, which you have, when you are running the shell.

While the webserver uses PHP 5.3 (which is fine), on the shell you have PHP 5.2 (which is not fine). If your wiki is hosted by someone, ask your host, how you can execute PHP 5.3 on the shell. The command for that might be something like php53 or so, but if that is possible and how depends on the host's setup.
