What are the potential errors in the PHP code provided for generating a dropdown list with selected options?

The potential error in the provided PHP code for generating a dropdown list with selected options is that the selected option is not being properly set based on the value retrieved from the database. To solve this issue, we need to compare each option value with the retrieved value and add the "selected" attribute to the matching option. 

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

    foreach ($options as $option) {
        if ($option == $selected_option) {
            echo "<option value='$option' selected>$option</option>";
        } else {
            echo "<option value='$option'>$option</option>";
        }
    }
    ?>
</select>
