What are the potential drawbacks of using the POST method for passing variables between scripts?

One potential drawback of using the POST method for passing variables between scripts is that the data is not visible in the URL, which can make debugging and troubleshooting more difficult. To solve this issue, you can use sessions to store and retrieve variables across multiple scripts.

// script1.php
session_start();
$_SESSION['variable_name'] = $_POST['variable_name'];
header('Location: script2.php');
exit;
```

```php
// script2.php
session_start();
$variable_name = $_SESSION['variable_name'];
echo $variable_name;
