RE: [PHP-DEV] Persistant global objects: WAS: RE: [PHP-DEV] ZendEngine2 availability

[Tyson Lloyd Thwaites]

I actually had a look at msession, and for a while I thought that was the
answer, but msession sends all its data through sockets...bye bye speed. I
made an Application object that used either msession or files as storage,
and files proved faster by about 2 times. But I want just RAM
storage...pervasive computing and all that. Otherwise msession would have
been perfect!!

Maybe there's a way to more tightly integrate it with PHP, so it send data
directly somehow (shm?), rather than through sockets...

RE: [PHP-DEV] Persistant global objects: WAS: RE: [PHP-DEV] ZendEngine2 availability

Something like that would be great. Do you mean store the *PHP object in
smh, after serialization, or do it on the Zend side from within an
extension? I guess what I am after is the ability to cache certain data
objects so that they can be retrieved with maximum speed, because there will
be thousands of them.



If these data objects could be written in C, and stored in some great global
washing basket in the sky, then that would just be great. Threaded access
will be an issue, but we can deal with that by using a single Application
object. I just have a feeling that all the serialize/deserialization that is
happening now will be bad for scalability, when it constantly needs to hit
the disk to create these objects.

Just a few thoughts. I would love to come up with a funky solution to this.

(PS: AFAIK ASP Application vars are actually stored in a seperate,
single-threaded containter. This is somewhat amusing, as many programmers
(myself included once :) store database connection objects in the
Application to save having to reconnect - little did we realise that there
might 100's of different requests all queueing up to use this single
connection...heh heh :)

Thanks for your help,

[PHP-DEV] Persistant global objects: WAS: RE: [PHP-DEV] ZendEngine2 availability

[Tyson Lloyd Thwaites]

Hi guys,

thanks for your help, I was able to get a Z2 build up and running.
Unfortunately it didn't appear to be quite stable enough for what I'm doing
yet, but at least it is cmoing along nicely!

One question while I'm here: I'm interested in persistant global objects,
like ASP's Application objects. I am sure this has been talked out on the
list before, but I did a quick search and couldn't find anything.

Is this possible?

Yesterday I wrote my first PHP test extension (Yay! I'm so happy - until now
I've been terrified of it!) I was able to register a class in the zend
engine (after to looking at the PECL stuff), but I was wondering whether I
could register a live, running object somewhere so that all scripts could
access it across requests? Would this maybe even require access to an
external engine written in C?

At the moment I have a static Application object in PHP that just writes
serialized objects to disk. This is not quite the same as having the object
staying in ram though. I have implemented a Factory class that creates data
objects and caches them to prevent database hits, and this speeds the
process up by about 400%. But there will be thousands and thousands of these
objects, and I would love to store them in RAM.

I know this sort of thing should really be written in Java, but I decided to
stick with PHP for this project so there is no going back!

Any comments, corrections, put-back-in-boxes, or thoughts on how to do this
will be ecstatically (get it? static? never mind) received.

Cheers
