How can switching from using $_GET to $_POST in PHP forms improve data security and prevent issues like the one described in the thread?

Switching from using $_GET to $_POST in PHP forms can improve data security by preventing sensitive information from being displayed in the URL. This can help prevent issues like data leakage, where sensitive information is exposed in the browser's address bar or in server logs. 

<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 PHP script `process_form.php`, you can access the form data using $_POST instead of $_GET:

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