请问怎么查询系统最近5天生成的txt文件并提供链接给访问者下载
系统生成的txt文件都保存在download文件夹下面，请问怎么找出最近5天生成的txt文件，并提供链接给访问者下载
文件的命名是：label+日期时间
Label20120929133440.txt
------解决方案--------------------
$t = date('Ymd', strtotime('-5 day'));
$res = array();
foreach(glob('download/label*.txt') as $fn) {
if(substr($fn, 5, 6) > $t) $res[] = $fn;
}
$res 就是
