RE: [PHP] Set Global Variables

Well, on unix, you could use the (still experimental, according to the docs) shared memory functions: http://php.he.net/manual/en/ref.shmop.php There's also the apparently more mature, but less portable semaphore/shared memory functions (also Unix only) here: http://php.he.net/manual/en/ref.sem.php I've never used either of these. Maybe you could explain what you're trying to do a bit more (and what platform you're on). I can't see where loading separate copies of the variables would be much of a memory issue, unless you have large numbers of variables, very long strings stored there, and hundreds of apache child processes. - steve At 2:52 PM -0400 4/11/02, RRamirez@LifeFiles.com wrote:

If I do that, won't the data that I fetch be duplicated in memory for each user? I'm trying to have just one space in memory allocated for these variables, sort of like the HTTP_SERVER_VARS. It seems that even if I do an autoprepend that file is going to run each time a user visits the site and a new memory space will be created for that variable. What I'm asking is how to set those constant server-wide global variables.

Is there a way to set a global variable that all users can access? I have some values in a database that I'm reading at the beginning of the session and carrying through out the session. The thing is, those values are the same for every user and instead of having a memory space for each users values I'd rather just use one memory space for all users.
