PHP5 object disappear between pages

[LePoulpe]

Hi,

This is certainly a stupid problem but it's driving me completly nuts.

I wrote an engine object with caching and stuff like that (using the singleton pattern) but each time I load the page, the class is reread ans the object is recreated !!!

I tried the simplest form of persistency with static global using

static $count;

if (!isset($count)) $count = 0;
$count++;

echo "count : $count";

but it always give me count=1 !!!

Is it normal ?
Is it a config problem either with php or apache (php as a module) ?
What's wrong ?

Thanks a lot for your help

I should have add that I'm handling a session in the same page. Is it the cause and how to work around ?

I don't use php5, but as far as I know static variables are not persisted over multiple pages. You can store $count in the session for that.

So, I should store a reference to my engine object in each session ? but create as many engine object as session ? And I can't share some db results between users ?

[mtmosier]

There's no session type way of sharing data between all users (like in asp for example), to the best of my knowledge. You could try the shared memory functions for this.

shared memory only works when using php as module, cli and cgi won't work.

i'm just playing around with an application class comparable to asp's application object which will be able to use shared memory, flat file and database
