querying 2 tables mixed results

hi guys me again doing a simple chat system very basic at the moment but stuck with if user A posts then user B then A then B all works ok but when user A posts twice it still displays A,B,A,B not AA,B,A
here is the script

PHP Code:

---

$result1 = mysql_query("SELECT * FROM sms WHERE touser = '$user' AND fromuser = '$fromuser' ORDER BY time");
$result2 = mysql_query("SELECT * FROM sms WHERE touser = '$fromuser' AND fromuser = '$user' ORDER BY time");
while($row1 = mysql_fetch_array($result1))
  {
echo $row1['message'];

while($row2 = mysql_fetch_array($result2))
  {
echo $row2['message'];
}
}

hey, I'm trying to rack up some 'thanks' on my profile so hook me up for this one!

you need to do some work with arrays here:

PHP Code:

---

$result1 = mysql_query("SELECT * FROM sms WHERE touser = '$user' AND fromuser = '$fromuser' ORDER BY time"); 
$result2 = mysql_query("SELECT * FROM sms WHERE touser = '$fromuser' AND fromuser = '$user' ORDER BY time"); 

$messages1 = mysql_fetch_array($result1);
$messages2 = mysql_fetch_array($result2);
 
$messages = array_merge($messages1, $messages2);

$sorted_messages = array_orderby($messages, 'time', SORT_DESC, 'touser', SORT_ASC);


echo '<pre>';
print_r($sorted_messages);
echo '</pre>';
