What is the difference between retrieving data from the POST array versus the GET array in PHP when navigating form steps?

When navigating form steps in PHP, the main difference between retrieving data from the POST array and the GET array is how the data is sent. Data sent using the POST method is not visible in the URL and is typically used for sensitive information like passwords. On the other hand, data sent using the GET method is visible in the URL, making it less secure but easier to bookmark or share. To retrieve data from the POST array, you can use the $_POST superglobal array in PHP. To retrieve data from the GET array, you can use the $_GET superglobal array. It's important to note that when navigating form steps, you should consider the sensitivity of the data being transferred and choose the appropriate method (POST for sensitive data, GET for non-sensitive data). 

// Retrieving data from the POST array
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    // Process the data as needed
}

// Retrieving data from the GET array
if ($_SERVER["REQUEST_METHOD"] == "GET") {
    $page = $_GET["page"];
    // Process the data as needed
}
