If a PHP extension such as XML or JSON is missing, the web installer will
fail with a PHP Fatal error even before the current environmental checks
happen. This isn't very user-friendly.
Perhaps the web installer could check for extensions that MediaWiki
unconditionally requires, and show an ugly, non-localized (yet useful)
error page if an extension is missing. Command-line scripts could also
make the same checks.
Perhaps the web installer checks could just run as part of the request
startup or shutdown sequence, even if only when a fatal error or
uncaught exception occurs.
