What are the potential challenges of inserting multiple values into a database when a checkbox is clicked in PHP forms?

When inserting multiple values into a database when a checkbox is clicked in PHP forms, the main challenge is handling the array of values that are submitted when multiple checkboxes are selected. To solve this issue, you can loop through the array of values and insert each value individually into the database. 

// Assuming the checkboxes have the same name attribute in the form
if(isset($_POST['checkbox_name'])){
    foreach($_POST['checkbox_name'] as $value){
        // Insert $value into the database
        // Make sure to sanitize the input to prevent SQL injection
    }
}
