[PHP-DB] Learning PHP Sessions From: Matthew Tedder (matthew <email protected>)

Hi,

    I'm new to PHP and am having trouble understanding how to use PHP
sessions. My book tells in near the beginning how to start them and register
session variables, but I can't figure out how to destroy a session or later
read those session variables. I'm also trying to do this across frames, but
can't even get it to work within a single page.

Here's what I've learned so far and what my problems are:
*/

/* To start a session */
session_start();

/* To register a session variable */
session_register("myvar");
$myvar = "some value";

/*
PROBLEM #1: From the above commands, I get a $PHPSESSID that seems to be
globally available for use, but I cannot seem to read my values back out of
the registered session variable from anywhere... I tried:
*/

print "$myvar\n"; /* and absolutely nothing is printed */

/* To destroy a session */
session_destroy();

/*
PROBLEM #2: This says there is no session to destroy. It's rather strange
because I can still print the $PHPSESSID value..

I've attached my code...

*/
