4. Connecting to the database

function &db_connect() {

require_once 'DB.php';

PEAR::setErrorHandling(PEAR_ERROR_DIE);

$db_host = 'localhost';
$db_user = 'shaggy';
$db_pass = 'password';
$db_name = 'shaggy';

$dsn = "mysql://$db_user:$db_pass@unix+$db_host/$db_name";

$db = DB::connect($dsn);

$db->setFetchMode(DB_FETCHMODE_OBJECT);
return $db;

}

This function connects to the database returning a pointer to a PEAR database object.

5. Session variables

To ease access to the current user's information we register it as session variables but to prevent error messages and set some defaults we use the following function.

function session_defaults() {

$_SESSION['logged'] = false;
$_SESSION['uid'] = 0;
$_SESSION['username'] = '';
$_SESSION['cookie'] = 0;
$_SESSION['remember'] = false;
}
... with a check like:

if (!isset($_SESSION['uid']) ) {
session_defaults();

}

to set the defaults. Of course session_start must be called before that.
