How can PHP developers ensure that the data fetched from a database is displayed correctly within option tags in select boxes?

When fetching data from a database to display within option tags in select boxes, PHP developers should ensure that the data is properly sanitized and escaped to prevent any potential security vulnerabilities or display issues. One way to achieve this is by using PHP's htmlspecialchars() function to encode special characters before outputting the data within the option tags. 

// Fetch data from database
$data = fetchDataFromDatabase();

// Output select box with fetched data
echo '<select>';
foreach ($data as $row) {
    echo '<option value="' . htmlspecialchars($row['value']) . '">' . htmlspecialchars($row['label']) . '</option>';
}
echo '</select>';
