php foreach正序倒序输出示例代码

实现代码：
// 正序foreach（$files as $file_num => $file） {if（is_file（$directory.$file））{//$file = iconv（"gb2312","UTF-8",$file）; //或者 iconv（"gb2312","UTF-8",$value）;$date = substr（$file,0,9）;echo "<li class="world-cup-".$date."">";echo "<a href="".$directory.$file."" rel="worldcup" title="巴西世界杯赛事".$date."">";echo "<img src="".$directory.$file."" alt="">";echo "</a>";echo "</li>";}}// 倒序foreach（array_reverse（$files） as $file_num => $file） {if（is_file（$directory.$file））{//$file = iconv（"gb2312","UTF-8",$file）; //或者 iconv（"gb2312","UTF-8",$value）;$date = substr（$file,0,9）;echo "<li class="world-cup-".$date."">";echo "<a href="".$directory.$file."" rel="worldcup" title="巴西世界杯赛事".$date."">";echo "<img src="".$directory.$file."" alt="">";echo "</a>";echo "</li>";}}
