PHP can be a suitable programming language for creating an online matrix form like the one described in the thread. PHP is a server-side scripting language that can handle form submissions and data processing efficiently. By using PHP along with HTML and CSS, you can create a dynamic matrix form that allows users to input data and submit it for processing.

<form method="post" action="process_form.php">
  <table>
    <?php
    $rows = 5;
    $cols = 5;
    
    for ($i = 0; $i < $rows; $i++) {
      echo "<tr>";
      for ($j = 0; $j < $cols; $j++) {
        echo "<td><input type='text' name='matrix[$i][$j]'></td>";
      }
      echo "</tr>";
    }
    ?>
  </table>
  <input type="submit" value="Submit">
</form>
