PHP文件目录操作问题列出目录下的东西时如何先列目录，再列文件文件也按照名称或时间排序或者类型...-优快云博客

<?php
$ar=array();

$d=dir(".");
while($f=$d->read()){
$ar['name'][]=$f;
$ar['type'][]=is_dir($f)?"dir":"file";
$ar['time'][]=date("Y-m-dH:i:s",filectime($f));
$ar['size'][]=filesize($f);
}
$d->close();

array_multisort($ar['type'],$ar['name'],SORT_STRING,SORT_ASC,$ar['time'],SORT_DESC,$ar['size']);

echo"<table>";
foreach($ar['name']as$k=>$v)
printf("<tr><td>%s</td><td>%s</td><td>%d</td><td>%s</td></tr>",$v,$ar['type'][$k]=="dir"?"[DIR]":"",$ar['size'][$k],$ar['time'][$k]);
echo"</table>";
?>

返回结果如下：
