PHP MYSQL存储会话数据，问题

Question

I would like to populate my $_SESSION array with all DB data of the relevant user that just logged in.

like "FIRST_NAME" in the DB would be $_SESSION["FIRST_NAME"];

What is the way to do that properly ?

$_SESSION = $result_set; //$result_set is the fetched array from the DB

Yielded an error (unknown() at line 0)

thanks in advance!

Don't do this. Store only the row ID in the session, and do a database request any time you need some information.

Storing this information in the session is completely redundant, and may lead to outdated data if the user changes something in the database that isn't reflected in the session variable.
