Hi, i'm using in each script: <? session_set_save_handler(...); //register my custom function to store session //into a mysql database session_start(); //session.auto_start is set to 0 in php.ini register_shutdown("session_write_close"); $object = unserialize($_SESSION['objectname']); //modify the object //.... $_SESSION['objectname'] = serialize($object); ?> When are exactly called the write and read function of my custom handler? Is it at the session_start that read function is called? or is it at $object = unserialize($_SESSION['objectname'])? Is write function called at session_write_close only? or any time $_SESSION[] is writted? Thanks a lot, I have no clue from PHP tutorial about this... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
