Beside this overwhelming description, PHP manual states it somewhere, but I can't recall it exactly where. Oooh, what fool me! it was discussed in session_register section: (http://www.php.net/manual/en/function.session-register.php) "Note: It is not currently possible to register resource variables in a session. For example, you can not create a connection to a database and store the connection id as a session variable and expect the connection to still be valid the next time the session is restored. PHP functions that return a resource are identified by having a return type of resource in their function definitions. A list of functions that return resources are available in the resource types appendix." BTW, when I worte my first PHP code, this note had not been added yet, and I also tried to register resources. ----- Original Message ----- From: "Martín Marqués" <martin@xxxxxxxxxxxxxxx> To: <pgsql-php@xxxxxxxxxxxxxx> Sent: Tuesday, November 13, 2001 10:49 PM Subject: Re: [PHP] db connections in session variables On Mar 13 Nov 2001 17:36, you wrote: > I was wondering if it were possible to store a database connection in a > session variable. No! Because the persistent connection gets opened with one child, and when you go for the next page you have very high probabilities (unless you have a very poor http configuration) of caching a new child, and not the old one. The problem comes here, just because the pconnect was done against the old child, and the new one doesn't know a thing about the pconnect you did before, so you'll allways (or almost always) an error of "wrong connection id".
