I have the following data in MySQL table:

| emp_id | date      |shift
| -------| ----------|------
| 1001   | 2022-08-01|M
| 1001   | 2022-08-02|M
| 1001   | 2022-08-03|N
| 1002   | 2022-08-01|M
| 1002   | 2022-08-02|E
| 1002   | 2022-08-06|M

Output should be like this (One Month list show):

| emp_id | 2022-08-01|2022-08-02|2022-08-03|2022-08-04|2022-08-05|2022-08-06
| -------| ----------|----------|----------|----------|----------|---------
| 1001   | M         |   M      |  N       |   0      |0         |  0
| 1002   | M         |   E      |  0       |   0      |0         |  M

What I have tried:

<pre>My code is:

     <?php
    for($j = 1; $j <=  date('t'); $j++)
    {
	$dat = str_pad($j, 2, '0', STR_PAD_LEFT). "-" . date('m') . "-" . 
    date('Y');
	$d[] = date('Y'). "-" . date('m') . "-" . str_pad($j, 2, '0', 
    STR_PAD_LEFT);
    $datess[] = str_pad($j, 2, '0', STR_PAD_LEFT)."<br>".date('D', 
    strtotime($dat));
    }
    ?>
	<?php 
    $link = mysqli_connect('localhost','root','','rostertest');
    if($link === false){
    die("ERROR: Could not connect. " . mysqli_connect_error());
    }
    ?>

    <div class="table-responsive">          
      <table class="table">
        <thead>
          <tr>
    <th>#</th>
    <th>Employee</th>
    <?php foreach($datess as $dates) {?>
    <th>
        <?php echo $dates; ?>
    </th>
	<?php } ?>
    </tr>
        </thead>
        <tbody id="tbl_body">
					
					<?php
					$i=0;
					$get_sql = "select * from ros";
					$run = mysqli_query($link,$get_sql);
					while($row = mysqli_fetch_array($run)){
					$date = $row['date'];
					$i++;
					?>
						<tr>
						<td><?php echo $i; ?></td>
						<td><?php echo $row['emp_id']; ?></td> 
						<?php foreach($d as $da) { if($date==$da){?>
						<td><?php echo $row['shift']; ?></td>
						<?php }else{ ?>
						<td><?php echo "0";?></td>
						<?php }}?>
						
					</tr>
					<?php }?>
				</tbody>
         </table>
        </div>

The technique you are looking for is called "pivoting" - it's not so easy in MySQL as others but there is a worked example here - Pivot Tables in MySQL[^]

To get your results exactly as you have shown them you will need to use IFNULL - MySQL :: MySQL 5.7 Reference Manual :: 12.5 Flow Control Functions[^]

Your expected results are mixing types 'E', 'M', 'N' then 0 (zero) so you will need to use something like IFNULL(`2022-08-02`,'0') etc i.e. the character '0' not the numeric 0
