  For a chessboard, we need to draw  64 boxes (8 rows and 8 columns) let us plan how we should proceed.
  

  • We should run two loops to create the 64 boxes.
  • The outer loop should run 8 times.
  • The inner loop should also run 8 times. So for each outer loop iteration, the inner loop will run 8 times.

  Now I am giving a code example in PHP, hope this will help you to understand the logic:

  <table border = '2'>
  <?php
  for($i=1; $i<9;$i++)
  {
      ?> <tr> <?php
      for($j=1; $j<9; $j++)
      {
          $total = $i+$j;
          if($total%2 == 0)
          {
              ?> <td style="background-color: black;" width = 80px; height = 80px;> </td><?php
          }
          else
          {
              ?> <td width = 80px; height = 80px;> </td><?php
          }
          
      }
      ?> </tr> <?php
  }
  ?>
  </table>

  Let me know if you have any further queries.
