global variables

giulioan

Hello,
I'm just starting out with php (version 3.0.18 is the one I have to work on) and I still

don't get one thing. I need to save an object as a global variable, in particular it is an

array that being very big and very heavy to obtain, I'd like to load it only once in my

application and then use it through. I tried to place it in the GLOBAL array

($GLOBALS['myarray'] = myarray), now the fact is that it looks like the page is recreating

the global variable every time, so that if I check wether it's set

(if(isset($GLOBALS['myarray']))) it never is and I can save nothing in it. Is there any

configuration setting I have to modify? I tried to save it also in other variables, like

$SERVER, or $SESSION (which, my experience coming from asp and jsp, I expected to be read

only) , but the behavior is the same.

Thank you for your help

$SERVER & $SESSION rnt available with php3...

u can load that array and save it to the session...

session_register("ses_aBigArray");

//register globals on
$ses_aBigArray = loadMyBigarray();

in bocca al lupo

you are right, the problem is I'd like to load the array really one time and not every new session, I read $GLOBALS was available since version 3.0, do you know how to have it working ?

Thank you very much

i dont think that a variable, not serialized in a file or in a db, can survive through sessions...

mmm and i think that the $GLOBALS array refers to the global scope of that script...

u want to load that array today and u want it available to every1 who use yr script in next 100 years? is it?

In any case, I found this in the Php manual

Note: Session handling was added in PHP 4.0.

sh....

any idea on how to serialize arrays to a file, or to a db (postgres) ???

Thanks again

Why not update to PHP 4 - there were a whole load of things added to PHP in version 4 that make life easier. Not that I'm in a position to judge - I've never used PHP3 and don't intend to try.

well, I just came to modify a fairly big application in php and I need to study what kind of problems could I have in the upgrade, if the change is quite safe then yes, that would be the best
