What are some best practices for processing checkboxes in PHP forms?

When processing checkboxes in PHP forms, it is important to check if the checkbox has been selected or not. This can be done by using the isset() function to determine if the checkbox value has been submitted. Additionally, checkboxes are treated as an array in PHP, so you may need to loop through the array to handle multiple checkboxes with the same name. 

if(isset($_POST['checkbox_name'])){
    // Checkbox is selected
    $checkbox_value = $_POST['checkbox_name'];
    // Process the checkbox value here
} else {
    // Checkbox is not selected
}
