What are the potential pitfalls of using a for loop to generate select options in PHP for a dropdown menu?

Using a for loop to generate select options in PHP for a dropdown menu can be problematic if the data source is not properly sanitized or validated. This can lead to potential security vulnerabilities such as SQL injection attacks. To mitigate this risk, it's important to properly escape and validate the data before using it to generate the select options. 

<select name="dropdown">
<?php
$dropdown_options = array("Option 1", "Option 2", "Option 3");

foreach ($dropdown_options as $option) {
    $safe_option = htmlspecialchars($option);
    echo "<option value='$safe_option'>$safe_option</option>";
}
?>
</select>
