$rows = array();
while($row = mysql_fetch_assoc($result)) {
    $rows[] = $row;
}

[EDITED]

Try:

$query="SELECT PatientMaster.FirstName,PatientMaster.LastName,ProviderAppointmentListings.AppointmentTime 
FROM PatientMaster JOIN ProviderAppointMentListings ON PatientMaster.PatientID = ProviderAppointmentListings.PatientId";

$result = mysql_query($query) or die(mysql_error());

If a MySQL error appears, then there must be something wrong with your query.
