sure,. But an ardinio boards and profram it to sense the voltage across
te LED by attaching it to the camera, and send the result down a USB
portto a computer running linux, and then write a daemon on C to monitor
that and place the state in a temporary file or somewhere where PHP can
see it.
Though quite why PHP is involved, its hard to say.

Ineptocracy
(in-ep-toc’-ra-cy) – a system of government where the least capable to lead are elected by the least capable of producing, and where the members of society least likely to sustain themselves or succeed, are rewarded with goods and services paid for by the confiscated wealth of a diminishing number of producers.
