How to echo all friends of for example id 2 from table usr_table with loop?
Tried this piece of code. but doesn’t work

$stmt = "SELECT fullname FROM usr_table INNER JOIN usrfrnd_table ON usr_table.id=usrfrnd_table.friend_id WHERE usrfrnd_table.user_id='$id'";
    $result=$db->query($stmt);
    foreach($result as $rec){
        echo "<li><a href=user.php?id=".$rec['id']."'>". $rec['fullname'] . "</a></li>";
    }

Try this:

$stmt = "SELECT id, fullname FROM usr_table INNER JOIN usrfrnd_table ON usr_table.id=usrfrnd_table.friend_id WHERE usrfrnd_table.user_id=2";
$result=mysql_query($stmt);
foreach($result as $rec){
    echo $rec['fullname'] . "<br>";
}
