Either you create a counter variable and increment that on each loop or swtich the while loop for a foreach. In that way, you can use the foreach($array as $key => $value) statement — Jose Henrique Felipetto

change the 2nd query

$qrygbr = mysqli_query($koneksi, "SELECT  @a:=@a+1 serial_number,t_gambar.* FROM t_gambar, (SELECT @a:= 0) AS a WHERE t_gambar.id_berita = '".$row['id']."'");

while ($rowgbr = mysqli_fetch_array($qrygbr, MYSQLI_ASSOC)) {
    echo $rowgbr['serial_number']; //this is you your needed serial number
}

The following should help you understand what you need to do. I've applied a $count variable within the loop to increase as the loop continues. I've added the variable to a

to show you how it works.

<?php
                                    $koneksi = mysqli_connect('localhost', 'admbumm_DedSec', 'omnimon786.,', 'admbumm_selipin');
                                    $qry = mysqli_query($koneksi, "SELECT * FROM t_berita ORDER BY tanggal DESC LIMIT 3");
                                    while($row = mysqli_fetch_array($qry, MYSQLI_ASSOC)){
                                        $qrygbr = mysqli_query($koneksi, "SELECT * FROM t_gambar WHERE id_berita = '".$row['id']."'");
                                        $rowcount=mysqli_num_rows($qry);
                                        $count = 1;
                                        while ($rowgbr = mysqli_fetch_array($qrygbr, MYSQLI_ASSOC)) { 
                                            # code...

you might want to add another variable inside your SQL Query like so $qry = mysqli_query($koneksi, "SELECT * FROM t_berita ORDER BY tanggal DESC LIMIT 3");

to $qry = mysqli_query($koneksi, "SELECT COUNT(*) as c,* FROM t_berita ORDER BY tanggal DESC LIMIT 3");

basically, SQL will count the total rows available and put it c. So you can just do some simple loop with c inside your PHP code
