How can one ensure that the form submission is indeed a POST request in PHP?

To ensure that a form submission is indeed a POST request in PHP, you can check the request method using the $_SERVER['REQUEST_METHOD'] variable. If the request method is 'POST', then the form submission is a POST request. You can use this check to validate the form submission method before processing the form data. 

if ($_SERVER['REQUEST_METHOD'] == 'POST') {
    // Process the form data
    // This code will only execute if the form submission is a POST request
} else {
    // Handle other request methods (e.g., GET)
}
