Hi

I needed to share some configuration information across requests.
The most straightforward way would be code it in a php file and include it
in every other script.
The problem with this approach is, the configuration script is executed on
every request.
The configuration data once figured out by the script remains the same for a
host, but the script to figure out the data could be arbitrarily complex.
The only mechanism I have figured out so far is to use the
shm_attach ,shm_get_var etc functions to store a single php array with all
my config in sysv shared memory.
So, the code to figure out the config runs only once and then populates the
shared mem, after that in every request, the config is read from the shared
memory.

Is this the only way to do this stuff (the main reason for my posting here)
?
Essentially I am looking for something like a static member data in java
which would stay up as long as the class is loaded (which would be across
arbitrary number of requests). For example any java servlet class. The php
static stuff goes away after each request.
I was hoping that stuffing things into $_SERVER would retain things across
requests. No such luck.

Is there a better solution than the SysV shared mem api.

P.S. I am using 4.3.4 apache 2.x and 1.x on linux (Fedora Core 3)
