How can values from a database be processed using checkboxes in PHP forms?

To process values from a database using checkboxes in PHP forms, you can first retrieve the values from the database and then dynamically generate checkboxes based on those values. When the form is submitted, you can check which checkboxes are selected and process the corresponding values accordingly in your PHP script. 

// Retrieve values from the database
// Assuming $values is an array of values retrieved from the database

// Generate checkboxes based on the retrieved values
foreach ($values as $value) {
    echo '<input type="checkbox" name="selected_values[]" value="' . $value . '">' . $value . '<br>';
}

// Process selected checkboxes when the form is submitted
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST['selected_values'])) {
        foreach ($_POST['selected_values'] as $selected) {
            // Process selected values here
            echo $selected . ' is selected.<br>';
        }
    }
}
