How can you ensure that checkbox values are properly accessed in PHP when using $_POST?

When dealing with checkbox values in PHP using $_POST, it's important to note that unchecked checkboxes do not get submitted in the form data. To ensure that checkbox values are properly accessed, you can check if the checkbox is set in the $_POST array using isset() function. This way, you can handle both checked and unchecked checkboxes effectively. 

// Check if the checkbox is set in the $_POST array and assign a default value if it's not set
$checkboxValue = isset($_POST['checkbox_name']) ? $_POST['checkbox_name'] : 'unchecked';

// Now you can use $checkboxValue in your code
