What is the recommended method for sending data to one page and opening another page in PHP?

When sending data to one page and opening another page in PHP, the recommended method is to use a form submission with the POST method to send the data to the first page, process it, and then redirect to the second page using header('Location: second_page.php'). This ensures that the data is securely transmitted and the user is directed to the intended page seamlessly. 

// First page (send_data.php)
if($_SERVER['REQUEST_METHOD'] == 'POST'){
    // Process the data sent from the form
    $data = $_POST['data'];

    // Redirect to the second page
    header('Location: second_page.php');
    exit;
}

// HTML form to send data
<form method="post" action="send_data.php">
    <input type="text" name="data">
    <button type="submit">Submit</button>
</form>
```

```php
// Second page (second_page.php)
// Retrieve the data sent from the first page
$data = $_POST['data'];

// Display the data on the second page
echo "Data received: " . $data;
