How to echo all friends of for example id 2 from table usr_table with loop?
Tried this piece of code, but it 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>";
    }

tried this one also 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>";

where am I wrong?

<?php
error_reporting(E_ALL);
require "db.php";

if(isset($_GET['id']))
{
    $id=$_GET['id'];
    $result=$db->query("SELECT * FROM usr_table WHERE id='$id' LIMIT 1") or die(printf("Səhv1: %s\n", $db->error));
    $data=$result->fetch_object();
    $fullname=$data->fullname;
    $dob = $data->dob;
    $phone= $data->phone;
    $adress= $data -> adress;
    $school = $data->school;
    $info = $data->info;}

    I believe that the trouble is in your PHP, not your SQL. Try this:

    $result = $db->query($stmt);
while ($rec = $result->fetch_array()) {
    echo "<li><a href=user.php?id=".$rec['id']."'>". $rec['fullname'] . "</a></li>";
}

    You appear to be using the mysqli extension. In that case, $db->query() returns a result object, not an array. You have to repeatedly call fetch_array() on the result object to get each row in the result set.

    Also, I recommend that you use this as your query (but that isn’t the immediate issue):

    select U.* from usr_table U
join usrfrnd_table F on U.id=F.friend_id
where F.user_id=2
union distinct select U.* from usr_table U
join usrfrnd_table F on U.id=F.user_id
where F.friend_id=2;
