What are the alternatives to using GET variables for passing data between URLs in PHP?

Using GET variables to pass data between URLs in PHP can expose sensitive information and make URLs longer and less readable. An alternative approach is to use POST requests to send data securely and invisibly between pages. This can be done by submitting a form with hidden input fields containing the data to be passed. 

<form method="post" action="destination.php">
    <input type="hidden" name="data1" value="value1">
    <input type="hidden" name="data2" value="value2">
    <button type="submit">Submit</button>
</form>
```

In the destination.php file, you can retrieve the data using $_POST superglobal:

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

echo "Data 1: " . $data1 . "<br>";
echo "Data 2: " . $data2;
