how do you set the session id?

[sneakyimp]

I have a PHP project which launches a FLASH application that needs to run database queries in the context of the current session. I know how to get variables into FLASH from the browser, I just need to know how to set the session id on PHP pages called from the flash application.

to send the data to flash, i can get the session id this way:

$my_session_id = session_id();  // send this to flash

then when flash POSTs data to my PHP page, this is my plan:

session_id($_POST[\'session_id_from_flash\']);

is this the proper way to handle things?

ok...i think i got it...

if i want my session id to be '1234567' i have to do this:

session_id('1234567');

before i call:

session_start();
