What are common pitfalls when using buttons within tables in PHP, and how can they be avoided?

Common pitfalls when using buttons within tables in PHP include not properly handling form submissions, not assigning unique identifiers to buttons, and not utilizing proper HTML form structure. To avoid these issues, ensure that each button has a unique name attribute, handle form submissions correctly, and structure your HTML form elements within the table properly. 

<form method="post" action="">
  <table>
    <tr>
      <td>Item 1</td>
      <td><button type="submit" name="delete_item1">Delete</button></td>
    </tr>
    <tr>
      <td>Item 2</td>
      <td><button type="submit" name="delete_item2">Delete</button></td>
    </tr>
  </table>
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  if (isset($_POST['delete_item1'])) {
    // Handle deletion of item 1
  }
  if (isset($_POST['delete_item2'])) {
    // Handle deletion of item 2
  }
}
?>
