这篇文章主要介绍了php中foreach正序输出与倒序输出的例子，php foreach用法实例，需要的朋友可以参考下
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>';
}
}
