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

When handling checkbox values in PHP forms, it's important to check if the checkbox was checked before accessing its value. This can be done by using the isset() function to determine if the checkbox was selected. If the checkbox was checked, you can then access its value using the $_POST superglobal array. 

// Check if the checkbox was checked
if(isset($_POST['checkbox_name'])) {
    // Access the value of the checkbox
    $checkbox_value = $_POST['checkbox_name'];
    // Perform further actions with the checkbox value
}
