What is the significance of the name attribute in PHP form handling?

The name attribute in PHP form handling is significant because it allows you to easily identify and access form input values submitted by the user. When processing form data in PHP, you can use the name attribute to retrieve specific input values using the $_POST or $_GET superglobals. This makes it crucial for correctly handling form submissions and interacting with user input.

<form method="post" action="process_form.php">
  <input type="text" name="username">
  <input type="password" name="password">
  <input type="submit" value="Submit">
</form>
```

In the PHP script "process_form.php", you can access the form input values using the name attribute like this:

```php
$username = $_POST['username'];
$password = $_POST['password'];
