What are the best practices for handling checkbox data in PHP forms?

When handling checkbox data in PHP forms, it's important to check if the checkbox was checked or not before processing the form data. This can be done by using the isset() function to determine if the checkbox value was submitted. If the checkbox was checked, its value will be included in the form data array. You can then use this information to perform the necessary actions in your PHP script. 

// Check if the checkbox was checked
if(isset($_POST['checkbox_name'])){
    // Checkbox was checked, perform action
    $checkbox_value = $_POST['checkbox_name'];
    // Process the checkbox value
} else {
    // Checkbox was not checked, handle accordingly
}
