php - Problems with echoing array values -


i having trouble echoing values array. using mysql query create array, $online, containing names of online users. here code:

<?php     $goodbye = time() - 300;     $qry="select username members seen >=$goodbye";     $result=mysql_query($qry);      if($result) {         $online = mysql_fetch_assoc($result);         foreach($online $u) {             echo $u;             echo "<br>";         }     } else {         die("query failed");     } ?>

when viewing on web page, first index of array shown (as in: if user1, user17, , user69 online, user1 appear on list). i'm sure happening because i'm using echo incorrectly, haven't been able figure out yet. tips? thanks.

you should loop (mysql_fetch_assoc)

if($result) {     while ($row = mysql_fetch_assoc($result)) {         echo $row["username"];     } }

also, notice warning.
