我们在学习Listing C的具体代码如下：

<ol class="dp-xml">
<li class="alt"><span><strong><font color="#006699"><span class="tag"></span><span class="tag-name">php</span></font></strong><span> </span></span></li>
<li class="alt"><span><span>$</span><span class="attribute"><font color="#ff0000">data</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">array</font></span><span>("US" =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> "United States", <br>"IN" =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> "India", "DE" =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> "Germany", "ES" =</span><span class="tag"><strong><font color="#006699">></font></strong></span><span> <br>"Spain");ksort($data); print_r($data);  </span></span></li>
<li class="">
<span></span><span class="tag"><strong><font color="#006699">?></font></strong></span><span> </span>
</li>
</ol>
