How can HTML source code be manipulated to hide query strings in PHP?

To hide query strings in PHP, you can use the POST method instead of the GET method when submitting form data. This way, the data will be sent in the request body instead of being visible in the URL. You can then access the form data using the $_POST superglobal in PHP. 

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

In the process.php file, you can access the form data like this:

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