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>';	}}
