What are some best practices for generating and handling dropdown menus in PHP?

When generating dropdown menus in PHP, it is important to properly handle the data being displayed in the dropdown and ensure that it is secure from any potential vulnerabilities like SQL injection. One best practice is to populate the dropdown menu options dynamically from a database or an array to ensure that the data is up to date and easily maintainable. 

// Example of generating a dropdown menu in PHP

// Array of options for the dropdown menu
$options = array("Option 1", "Option 2", "Option 3");

// Generate the dropdown menu
echo '<select name="dropdown">';
foreach ($options as $option) {
    echo '<option value="' . $option . '">' . $option . '</option>';
}
echo '</select>';
