ID: 19694 Comment by: okapi at yahoo dot com Reported By: citd at mediaways dot net Status: Open Bug Type: Feature/Change Request Operating System: N/A PHP Version: 4.2.3 New Comment:
I'm suprised why something along these lines isn't incorporated into PHP such that there's an application process that could handle application scope variables (and query caching). It seems this kind of issue would make it match up better with ASP and Cold Fusion. Is anyone aware of such an effort?

(OK SSJS can interchange data via the project-variable. But, at leat in our project, i can't see the point for this.) For our project a global and persistent variable is important for SPPPPPEEEEEDDDDDD (and cost. We don't have to buy more frontend-machines to compensate the performance losse of PHP compared to SSJS). Having to parse the configuration for every request just kills the performance. ------------------------------------------------------------------------ [2002-10-01 12:23:18] [EMAIL PROTECTED] what about using shared memory? http://www.php.net/manual/en/ref.sem.php http://www.php.net/manual/en/ref.shmop.php ------------------------------------------------------------------------ [2002-10-01 10:19:10] citd at mediaways dot net In "Serversite Javascript" exists the (global) "project" variable. The content of this variable is persistent as long as the Web-Server isn't restarted. This concept is IMHO great for e.g. configuration-variables. Load the configuration once and be done with it until the web-server is restarted. In a project i'm assigned to the configuration is stored in a Oracle-DB. As the configuration must only be parsed once after restarting the web-server the cost of about 2 seconds is no problem at all. In PHP we would have to do this every time a uses requests a page, which is to costly. Currently seems like we have to make an external "Configuration2PHP"-Script which fetches the current configuration and makes a static (PHP-)file out the configuration. (The "application" is "stateless", so it can't be achieved over a session. (->reading the config-reading once per user). And the application is running on many web-servers. With the stateless design the load-balancing is easier as you don't have to "bind" a session to a specific web-server or making a DB-Session or something similar. And you don't have problems with expired/stalled sessions.) "Better(tm)" would be if a concept like a persistent variable is introduced. IMO others would appreciate that too. :-) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=19694&edit=1
