i'm making table reservations scheduling table with PHP and Mysql. i'm stuck on one thing, dont know how to check every cell i must print,which will indicate a reservation, with every column,which will indicate hours. Can anyone give me an idea ? i will get my reservation info from database same as all tables there are in restaurant. It will look something like this:

<table>
  <tbody>
      <th>10:00</th>
      <th>11:00</th>
      <th>12:00</th>
      <th>13:00</th>
        . . .


    <tr>
     <td>Table Nr.1</td>
     <td>check if 10:00 = reservation_time ...</td>
   </tr>
   <tr>
     <td>Table Nr.2</td>
     <td>check if 11:00 = reservation_time ...</td>
   </tr>
  <tbody>
</table>

i will print working time from database using for loop,because every restaurant has it's own working time. Same goes to Table number. i will loop all tables from database.

It should look something like this in the end : 84b6b241634099bfed5f100b38135b5c ![84b6b241634099bfed5f100b38135b5c]

i will give you better presentation of what i need.

echo'
        <table>
            <tbody>
                <th>Table/Hours</th>
    ';
    for($i = $start; $i <= $end ; $i++)
    {
        echo '<th>'.$i.'</th>';
    }

    while($table = mysqli_fetch_assoc($tables))
    {
            echo '<tr>
                     <td>'.$table['ID'].'</td>';

                        for($i = $start_work_hour; $i <= $end_work_hour; $i++)
                        {
                            ..database things....

                            if($reservation_time == $i)
                            {
                                echo '
                                    <td colspan="there goes variable with reservation duration time,say,2h" style="background-color: red">
                                        '.$fname.'
                                        '.$lname.'
                                    </td>
                                ';

                            }
                            else
                            {
                                echo'<td style="background-color: green">FREE</td>';

                            }

                        }
                echo'  </tr>';
    }
    echo '</tbody>
        </table>
        ';

i dont have any trouble when i have only on reservation per day on the same table, same if table isnt in reservation table in database,it just prints for all hours FREE. However, if i have more than on reservations on the same table. i dont know how to put them that it would be like: FREE,FREE,FREE,BUSY,FREE,BUSY,BUSY.
