What are the advantages and disadvantages of using hidden input fields versus sessions to pass data between multiple pages in PHP?

When passing data between multiple pages in PHP, using hidden input fields can be advantageous because the data is directly embedded in the HTML form and can be easily accessed by the receiving page. However, hidden input fields can also be manipulated by users, posing a security risk. On the other hand, using sessions to pass data between pages is more secure as the data is stored on the server-side, but it requires additional server resources and may not be suitable for all scenarios. 

// Using hidden input fields to pass data between pages
<form action="page2.php" method="post">
    <input type="hidden" name="data" value="example">
    <button type="submit">Submit</button>
</form>
```

```php
// Using sessions to pass data between pages
//page1.php
session_start();
$_SESSION['data'] = "example";
header("Location: page2.php");

//page2.php
session_start();
$data = $_SESSION['data'];
echo $data;
