Forms let users send data to your server.
  
  ## Simple contact form
  
  ```html
  <form method="post">
    <input name="name" placeholder="Name">
    <input name="email" placeholder="Email">
    <button>Send</button>
  </form>
  ```
  
  ## PHP handling
  
  ```php
  <?php
  if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    $name = trim($_POST['name'] ?? '');
    $email = trim($_POST['email'] ?? '');
  
    if ($name === '' || $email === '') {
      echo "All fields required";
    } else {
      echo "Thanks, $name";
    }
  }
  ?>
  ```
  
  ## Security tip
  
  Always validate and sanitize user input.
