PHP remote file management, can give table sorting, traversal directory, time sorting _php tips

Copy Code code as follows:

<?php
$rootdir = "./";
$spacenum = 0;
$filenum = 0;
$allfilesize = 0;
echo "echo "<a href= ' > Reset </a>";
Readlogdir ($rootdir);
echo "echo "Total files Count: $filenum .<br>";
echo "Total disk space used: $allfilesize <br>";
$freespace =diskfreespace ("/");
echo "Residue disk space: $freespace <br>";
function Readlogdir ($subdir) {
Global $rootdir, $spacenum, $filenum, $allfilesize;
@chdir ($subdir) or Die ("Error:could not on" to this directory!);
$dirobject =dir ($subdir);
echo "<table width=600 border=0 align= ' center ' id= ' Clearstart ' ><tr ' the id= ' Ignore ' ><td's width=40% ' Jm_powerlist (0) ' ><b> filename </b></a></td><td width=20% onclick= ' jm_powerlist (1) ' > <b> File size </b></td><td width=40% onclick= ' jm_powerlist (2) ' ><b> creation time &LT;/B&GT;&LT;/TD ></tr> ";
$i = 0;
while ($file = $dirobject->read ()) {
if ($file = = "." | | $file = = "...") {
Continue
}
$i = $i +1;
echo "<tr bgcolor= ' #e0e0e0 ' ><td>". $i. " <a href=.php?file_dir= ". $rootdir." &file_name= ". $file." Target=_blank> ";
echo $file. " </a></td><td> ". Number_format (FileSize ($file)/1024, 2, '. ', '). " Kb</td><td> ". Date ("Y-m-d h:i:s", Filemtime ($file)). "</td></tr>";
$allfilesize +=filesize ($file);
$filenum + +;
}
echo "</table>";
Return
}
