How can I prevent users from seeing variables in the URL in PHP?

To prevent users from seeing variables in the URL in PHP, you can use the POST method instead of the GET method when submitting forms. This way, the form data is sent in the request body rather than in the URL, making it less visible to users. 

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

In the process_form.php file, you can access the form data using the $_POST superglobal array:

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