PHP Shuffle Array提高输出？

Question

I am using the following tutorial to learn how to shuffle in PHP, but the output is ugly. How do I change the output of the shuffle to be more in line with the poll I want to display in list format?

I am using the following tutorial to learn how to do this:

http://www.w3schools.com/php/func_array_shuffle.asp

<?php
$my_array = array("a" => "Dog", "b" => "Cat", "c" => "Horse");

shuffle($my_array);
print_r($my_array);
?

But the output is ugly: Array ( [0] => Cat [1] => Dog [2] => Horse )

How do I make the shuffle array look nice an pretty like this?

<ul>
<li><input id="pollRadioButton1" name="pollAnswerID" type="radio" value="1" /> Answer1 for Poll1</li>
<li class="pollChart pollChart1">&nbsp;</li>
<li><input id="pollRadioButton2" name="pollAnswerID" type="radio" value="2" /> Answer2 for Poll1</li>
<li class="pollChart pollChart2">&nbsp;</li>
</ul>

Answer 1

<?php

    $my_array = array("a" => "Dog", "b" => "Cat", "c" => "Horse");
    shuffle($my_array);

?>
<ul>
    <?php foreach ($my_array as $key => $element): ?>
        <li>
            Whatever you want to do with
            <?php echo htmlspecialchars($element) ?>
            (<?php echo htmlspecialchars($key) ?>).
        </li>
        <li class="pollChart pollChart1">&nbsp;</li>
    <?php endforeach ?>
</ul>
