PHP numbering by unique ID grouping - php

Question

I want to auto numbering but by user group
Query :
$query = "select distinct(DATE_FORMAT(a.in_time, '%Y%m%d')) as in_time, a.user_id, a.notes, b.nama from attendance a left join dat_login b on(a.user_id=b.ID) where DATE_FORMAT(a.in_time, '%Y')='2017' and DATE_FORMAT(a.in_time, '%M')='April' and id_shop!=2 order by b.nama asc";
$querynm = "select distinct(b.nama) as nama from attendance a left join dat_login b on(a.user_id=b.ID) where DATE_FORMAT(a.in_time, '%Y')='2017' and DATE_FORMAT(a.in_time, '%M')='April' group by b.nama order by b.nama asc";
$stid = mysqli_query($conn, $query) or die (mysqli_error($conn));
$stnm = mysqli_query($conn, $querynm) or die (mysqli_error($conn));
Result :
$alphabet_start = 'A';
while ($data = mysqli_fetch_assoc($stid)) {
$data['user_id'] += 1;
$no_cell = 11;
echo $data['nama'] . " ";
echo $data['user_id'] . " ";
if ($data['notes']=="") {
echo chr(ord("A") + date('d', strtotime($data['in_time']))) . $no_cell . " - " . chr(ord("A") + date('d', strtotime($data['in_time']))) . ". " . "Masuk <br>";
} else if ($data['notes']=="S") {
echo chr(ord("A") + date('d', strtotime($data['in_time']))) . $no_cell . " - " . chr(ord("A") + date('d', strtotime($data['in_time']))) . ". " . "Sakit <br>";
} else if ($data['notes']=="L") {
echo chr(ord("A") + date('d', strtotime($data['in_time']))) . $no_cell . " - " . chr(ord("A") + date('d', strtotime($data['in_time']))) . ". " . "Libur <br>";
}
$alphabet_start++;
$no_cell++;
$data['user_id']++;
}
But, the value showing like this :
I want the value showing like this :
As you can see the number is changing in the next name, how to do it ?
Sorry for my bad grammar. Thanks before :)

Your code is a bit confusing but I think I understand what you mean.
You can do it as such:
$alphabet_start = 'A';
$userID = "";
$cells = array();
$cellNum = 11;
while ($data = mysqli_fetch_assoc($stid)) {
$data['user_id'] += 1;
if (in_array($data['user_id'], $cells)) {
$no_cell = $cellNum;
} else {
$no_cell = ($cellNum += 1);
$cells[] = $data['user_id'];
}
echo $data['nama'] . " ";
echo $data['user_id'] . " ";
if ($data['notes'] == "") {
echo chr(ord("A") + date('d', strtotime($data['in_time']))) . $no_cell . " - " . chr(ord("A") + date('d', strtotime($data['in_time']))) . ". " . "Masuk <br>";
} else if ($data['notes'] == "S") {
echo chr(ord("A") + date('d', strtotime($data['in_time']))) . $no_cell . " - " . chr(ord("A") + date('d', strtotime($data['in_time']))) . ". " . "Sakit <br>";
} else if ($data['notes'] == "L") {
echo chr(ord("A") + date('d', strtotime($data['in_time']))) . $no_cell . " - " . chr(ord("A") + date('d', strtotime($data['in_time']))) . ". " . "Libur <br>";
}
$alphabet_start++;
$no_cell++;
$data['user_id']++;
}
