What is the purpose of using PHP variables to fill HTML select options?

Using PHP variables to fill HTML select options allows for dynamic and flexible content generation within the select element. This approach enables developers to easily populate the dropdown list with data from a database, an array, or any other data source. By using PHP variables, the select options can be generated dynamically based on the specific requirements of the application, making the code more maintainable and scalable.

<select name="example">
  <?php
    $options = array("Option 1", "Option 2", "Option 3");
    foreach ($options as $option) {
      echo "<option value='$option'>$option</option>";
    }
  ?>
</select>
