How can a dropdown menu be integrated into a registration script in PHP?

To integrate a dropdown menu into a registration script in PHP, you can create a select element within a form that allows users to choose an option from a list of predefined values. This dropdown menu can be used to collect specific information from users during the registration process, such as their country, gender, or preferred language.

<form action="registration.php" method="post">
    <label for="country">Country:</label>
    <select name="country" id="country">
        <option value="USA">United States</option>
        <option value="CAN">Canada</option>
        <option value="UK">United Kingdom</option>
        <!-- Add more options as needed -->
    </select>
    <input type="submit" value="Register">
</form>
