What are the best practices for naming and handling form fields in PHP when submitting data from dynamically generated tables?

When submitting data from dynamically generated tables in PHP, it is important to properly name and handle form fields to ensure that the data is correctly processed. One best practice is to use array notation in the field names to group related data together. This allows you to easily loop through the submitted data and process it accordingly. 

<form method="post">
  <?php
  foreach ($tableData as $row) {
    echo '<input type="text" name="field[' . $row['id'] . '][name]" value="' . $row['name'] . '">';
    echo '<input type="text" name="field[' . $row['id'] . '][age]" value="' . $row['age'] . '">';
  }
  ?>
  <input type="submit" name="submit" value="Submit">
</form>

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
  if (isset($_POST['field'])) {
    foreach ($_POST['field'] as $id => $data) {
      $name = $data['name'];
      $age = $data['age'];
      // Process the data as needed
    }
  }
}
?>
