- Persistant per-process scripting
Apache 1.3 has added things that makes this much easier than before.
The module structure now contains a child_init hook and a child_exit
hook where you can register functions to be called when an httpd
process starts up and when one shuts down (due to MaxRequestsPerChild
or a Kill). The only real trick now is to come up with some sort of
syntax for specifying what to do from the child_init call and the
child_exit call.
One idea is to be able to add a <PHP>...</PHP> block to the Apache
httpd.conf file which would somehow define a series of PHP statements
to be executed from the child_* calls. One for startup and another
block for shutdown. These blocks would work with the per-process
memory pool, so any variables initialized here would have a lifespan
equal to that of the httpd process. Basically request-spanning
global variables.
