Session Handling

sam · June 9th, 2003, 04:28 PM

Hi all,
1) On page 222 it has a function db_error_message() is this an internal PHP function or was it supposed to be written b/c I'm getting the error: Fatal error: Call to undefined function: db_error_message() in /usr/htdocs/php/handler.php on line 99

2) Does anybody have a "default" session handling example they can point me to, (why did the author use a db anyway)?
Thanks,
Sam

db_error_message() is a user-defined function. If you copied that code out of the book, then that function should also be defined in that book somewhere.

Here's a simple session example:

Code:

<?php
session_start();

if (!isset($_SESSION['count']))
{
   $_SESSION['count'] = 0'
}

echo "You've seen this page " . ++$_SESSION['count'] . " time(s).\n";
?>

Take care,

Nik
