Are there best practices for handling checkbox data transmission in PHP forms?

When handling checkbox data transmission in PHP forms, it's important to ensure that unchecked checkboxes are not transmitted as empty values. One way to achieve this is by using isset() function to check if the checkbox is set before processing the form data.

// Check if the checkbox is set and assign a default value if not checked
$checkbox_value = isset($_POST['checkbox_name']) ? $_POST['checkbox_name'] : 0;

// Use the $checkbox_value in further processing of the form data
