How can HTML elements be named in PHP to automatically create arrays for data processing?

When HTML elements are named with square brackets in PHP, it automatically creates arrays that can be easily processed in PHP. This is useful when dealing with form submissions or handling multiple inputs with similar names. By naming HTML elements in this way, PHP can automatically parse the data into arrays for easier manipulation. 

<form method="post">
  <input type="text" name="user[name]">
  <input type="text" name="user[email]">
  <input type="text" name="user[phone]">
  <input type="submit" value="Submit">
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  $userData = $_POST['user'];
  
  // Accessing individual values
  $name = $userData['name'];
  $email = $userData['email'];
  $phone = $userData['phone'];
  
  // Processing the data further
  // ...
}
?>
