Hi! So this is the only way I guess ...
Do you propose to serialize() the objects in the tree and write that data into a shared memory block, and then deserialize them at the beginning of each script that needs the data back into objects ? I would think that that would impose the same performance penaltys from creating the objects again (this seems to be what slows php down), only the reading process ist sped up ... not exactly what I would like, but seems PHP provides no other functionality ... mathias rockel ----- Original Message ----- From: "Philip Hallstrom" <[EMAIL PROTECTED]> To: "Mathias Rockel" <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Tuesday, January 14, 2003 5:26 PM Subject: [PHP] Re: Persistent global data ? > http://www.php.net/manual/en/ref.shmop.php > > On Tue, 14 Jan 2003, Mathias Rockel wrote: > > > Hi all ! > > > > It seems I did not state exactly enough what I need ... if I use the > > $_SESSION functions or write the stuff myself makes no difference, actually > > then I can just leave it in the database and read it every time ... but that > > is just slow ...
