What are some best practices for integrating PHP with HTML to create dynamic dropdown menus?

When integrating PHP with HTML to create dynamic dropdown menus, it is best practice to use PHP to generate the dropdown menu options dynamically based on data retrieved from a database or other source. This allows for easy updates and maintenance of the dropdown menu without having to manually edit the HTML code. Additionally, using PHP to populate the dropdown menu ensures that the menu is always up-to-date with the latest data.

<select name="dropdown">
    <?php
    // Retrieve data from database
    $options = array("Option 1", "Option 2", "Option 3");

    // Loop through options and generate dropdown menu
    foreach ($options as $option) {
        echo "<option value='" . $option . "'>" . $option . "</option>";
    }
    ?>
</select>
