What is the significance of the $_POST['sent'] method in PHP form handling?

The $_POST['sent'] method in PHP form handling is significant because it allows the form to be submitted and processed only when the 'sent' parameter is present in the POST request. This helps prevent the form from being submitted multiple times or without proper validation. To implement this, you can check if the 'sent' parameter is set in the $_POST array before processing the form submission.

if(isset($_POST['sent'])) {
    // Process form submission
    // Add your form processing logic here
}
