What are the differences between the POST and GET methods in form submission and how does PHP handle the data received?

When submitting a form, the main differences between the POST and GET methods are that POST sends form data in the HTTP request body, while GET sends it in the URL. PHP handles data received from both methods using superglobal arrays. To access form data submitted via POST, you can use $_POST['input_name'], and for data submitted via GET, you can use $_GET['input_name']. 

// Handling form submission using POST method
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $input_data = $_POST['input_name'];
    // Process the input data as needed
}

// Handling form submission using GET method
if ($_SERVER["REQUEST_METHOD"] == "GET") {
    $input_data = $_GET['input_name'];
    // Process the input data as needed
}
