How can you handle unchecked checkboxes in PHP when using POST?

Unchecked checkboxes do not get included in the POST data when a form is submitted. To handle unchecked checkboxes in PHP when using POST, you can check if the checkbox value is set in the $_POST array. If it is not set, you can assign a default value to represent the unchecked state. 

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

// Use the $checkbox_value variable in your code
