I'm not quite sure what your question is, but here's some info. You have to call session_start() before using anything in the session. This must be called before there is any output to the browser. After the call to session_start() you can get/set/unset any session value you want at any time in the script (all of this is stored on the server). The best way to do all of this is through the $_SESSION superglobal. Use it like a normal assicative array: $_SESSION['var'] = 'value'; or: $_SESSION['array'] = array(1, 2, 3, 4); os: $_SESSION['object'] = new Object(); Everything you put in there will be available from any function without having to use the global keyword or the $GLOBALS superglobal. Note that you can't store recources in the session (at least, they can't be used as resources on subsequent requests.) This includes things such as open file desriptors and database connections or statement handles. -- DB_DataObject_FormBuilder - The database at your fingertips http://pear.php.net/package/DB_DataObject_FormBuilder paperCrane --Justin Patrin-- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
