PHP remote file management, you can sort tables, traverse directories, and sort by time_PHP tutorial

Copy code The code is as follows:

$rootdir="./";
$spacenum=0;
$filenum=0;
$allfilesize=0;
echo "

文件管理调试测试

";
echo "重置";
readLogDir($rootdir);
echo "

---

";
echo "Total files count: $filenum.
";
echo "Total disk space used: $allfilesize
";
$freespace=diskfreespace("/");
echo "residue disk space: $freespace
";
function readLogDir($subdir){
global $rootdir,$spacenum,$filenum,$allfilesize;
@chdir($subdir) or die ("error:could not change to this directory!");
$dirobject=dir($subdir);
echo "";
$i=0;
while ($file=$dirobject->read()){
if($file=="." || $file==".."){
continue;
}
$i=$i+1;
echo "";
$allfilesize+=filesize($file);
$filenum++;
}
echo "

文件名	文件大小	创建时间
".$i.""; echo $file."	". number_format((filesize($file)/1024),2,'.','')."KB	". date("Y-m-d H:i:s", filemtime($file)). "

";
return;
}
?>
