How can PHP developers ensure that only selected checkboxes update specific values in a database table?

To ensure that only selected checkboxes update specific values in a database table, PHP developers can use an if statement to check if a checkbox is selected before updating the corresponding value in the database. By iterating through each checkbox input and checking its status, developers can selectively update only the values associated with the selected checkboxes. 

// Assuming checkboxes are named 'checkbox[]' and values are associated with each checkbox

if(isset($_POST['checkbox'])) {
    foreach($_POST['checkbox'] as $value) {
        // Update database table with specific value based on checkbox selection
        // Example SQL query: UPDATE table SET column = 'new_value' WHERE id = $value
    }
}
