In what scenarios is it advisable to use POST over GET for form submissions in PHP, especially when dealing with large amounts of data?

When dealing with large amounts of data in form submissions in PHP, it is advisable to use POST over GET to prevent the data from being visible in the URL and to avoid any length restrictions that GET requests may have. POST requests also provide better security as the data is sent in the request body rather than in the URL. 

<form method="post" action="submit.php">
  <input type="text" name="data1">
  <input type="text" name="data2">
  <input type="submit" value="Submit">
</form>
```

In the PHP file "submit.php", you can access the submitted data using the $_POST superglobal array:

```php
$data1 = $_POST['data1'];
$data2 = $_POST['data2'];

// Process the submitted data here
