php foreach正序倒序输出示例代码
实现代码：
//正序
foreach($filesas$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'<liclass="world-cup-'.$date.'">';
echo'<ahref="'.$directory.$file.'"rel="worldcup"title="巴西世界杯赛事'.$date.'">';
echo'<imgsrc="'.$directory.$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'<liclass="world-cup-'.$date.'">';
echo'<ahref="'.$directory.$file.'"rel="worldcup"title="巴西世界杯赛事'.$date.'">';
echo'<imgsrc="'.$directory.$file.'"alt="">';
echo'</a>';
echo'</li>';
}
}
