What are some best practices for handling checkbox values in PHP form submissions?

When handling checkbox values in PHP form submissions, it is important to check if the checkbox was checked or not before processing the form data. This can be done by using isset() function to determine if the checkbox value was submitted. If the checkbox is checked, its value will be included in the form data; otherwise, it will not be present. 

// Check if the checkbox was checked
$checkbox_value = isset($_POST['checkbox_name']) ? $_POST['checkbox_name'] : 'unchecked';

// Process the form data based on the checkbox value
if($checkbox_value == 'checked'){
    // Checkbox was checked
    // Perform necessary actions
} else {
    // Checkbox was not checked
    // Perform alternative actions
}
