how to receive message in xmpphp

Question

it is clearly stated in the examples how to send message but, i am not clear with how to receive messages initiated by other client in the server any help is highly appreciated

Here is my code for sending the message

include("xmpphp/xmpp.php");

//username = user without domain, "user" and not "user@server" - home is the resource
$conn = new XMPPHP_XMPP('localhost', 5222, 'robel27', 'yoyene122127', 'kiyos');
// Enables TLS - enabled by default, call before connect()!
$conn->useEncryption(false);

$conn->connect();
 // shows the user's status message
$conn->presence();
$conn->processUntil(array('session_start', 'roster_received'));
$conn->processTime(2);
$conn->message('kiyos12@kiyos', $_POST['msg1']);
$conn->disconnect();

To get messages you can use $data = $conn->processUntil('message');
