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) 3 1811
Can you serialize the configuration data into a database or text file?

That is what I do. I resigned myself to the fact that in a stateless web
application every request basically restarts the whole application all
over again (apart from possible persistent $_SESSION variables).
A few years ago I attended a talk about persistent PHP objects (it was
called "PHP Bananas", very clever, supposed to be the PHP version of
"Java Beans" if I understood things correctly), something that could
help to get more 'state' in web apps, but I don't know if that project
is still active or how far they got.

I'm not familiar with those functions. Wouldn't a session also work in
your case (since you are only storing an array)?

Hi,
Is there a mechanism within PHP for sharing data over
multiple requests that are not tied to a specific session.
I need to write a memory senstive cache in pure PHP. I
have an application which needs to store documents
from an application server elsewhere, due to the data
within the documents I can't write them to disk and I
have to minimise the amount of accesses to the server.

Hi
I have a site where I would like some pages to be accessed via SSL (login
and payment etc) and others via regular http. However I'm not sure whether
Session state can be maintained between the 2 protocols.
We have SSL set up on the site so that it can be accessed via the same
domain:

Is there a way to get a user control to remember its state across pages? I
have a standard page layout I use with a header and footer as user controls.
Each page uses the same layout by means of copy paste (I hear this will
improve in ASP.Net 2 via master pages).
When I navigate from one page to the next the header and footer user
controls lose their state because they are effectively different instances
of the user control.

I have to interface to a third-party application that receives HTTP

Also, if I repeatedly open new connections to it, the server gets

I have a web farm that uses a state server for session management.
A user logs on to a website (www1.mysite.com).
When the same user visits www2.mysite.com I want the user to be logged in.
Right now it he is not logged in on www2.mysite.com (both sites use the same
state server).
The reason for this seems to be that the user gets a new SessionId when he
visits a new web server (www2.mysite.com for example).
