Creating custom classes

[NFicano]

I wanted to build custom classes to divide up and organize my applications functionality. I'm using PHP PEAR's liveUser and MDB2 packages. Now normally, to interact with liveUser, you must use require_once to point to the config file (a file that stores several object instances, configuration preferences etc).

 

For example, to update the current users password:

require_once '../../sys/conf.php';

// check if a user is logged in
if (!$LU->isLoggedIn())
{
// path to login form
    include_once '../../sys/login.php';

// exit script
    exit();
}

// get username
$handle = $LU->getProperty('handle');

$filter = array('container' => 'auth','filters' => array('handle' => $handle));

// get user id
$user_id = $LUA->getUsers($filter);

$data = array('passwd' => 'new_password');

$updatedUser = $LUA->updateUser($data, $user_id[0]['perm_user_id']);

 

now if I wanted to divide up and group similar functionality into classes, how would I interact with the instances declared in the configuration file? Whenever I try to build a class with multiple functions such as:

 

require_once '/sys/conf.php';

// check if a user is logged in
if (!$LU->isLoggedIn())
{
// path to login form
    include_once '/sys/login.php';

// exit script
    exit();
}

class mgmt
{
function new_passwd($new_passwd)
{		
	// get username
	$handle = $LU->getProperty('handle');

	$filter = array('container' => 'auth','filters' => array('handle' => $handle));

	// get user id
	$user_id = $LUA->getUsers($filter);

	$data = array('passwd' => $new_passwd);

	$updatedUser = $LUA->updateUser($data, $user_id[0]['perm_user_id']);
}
function change_name($new_name)
{
	// get username
	$handle = $LU->getProperty('handle');

	$filter = array('container' => 'auth','filters' => array('handle' => $handle));

	// get user id
	$user_id = $LUA->getUsers($filter);

	$data = array('passwd' => $new_name);

	$updatedUser = $LUA->updateUser($data, $user_id[0]['perm_user_id']);
}
}

$a = new mgmt;
$a->new_passwd("test123");
$a->change_name("Joe");

 

I get: "Notice: Undefined variable: LU" and Call to a member function getProperty() on a non-object
