Are there any best practices for handling checkbox values in PHP forms to ensure accurate data submission?

When handling checkbox values in PHP forms, it's important to check if the checkbox was checked 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. Here is an example of how to handle checkbox values in PHP forms: 

// Check if the checkbox was checked
if(isset($_POST['checkbox_name'])){
    $checkbox_value = $_POST['checkbox_name'];
    // Process the checkbox value
    // You can also assign a default value if the checkbox was not checked
} else {
    // Checkbox was not checked, handle accordingly
}
