PHP self-test script -- need suggestions

A client has an account on a vendor's server.  We have no control over system updates/parameters.
About once a week something will happen that breaks some facet of PHP.
the most common is suhosin either gets protected or uninstalled.
example error:


Please offer experience/advice/suggestions for a script  that can be run in an (hourly) cron job that checks basic PHP health (including suhosin)  and if there's a problem
emails the error to us.

thanks
