如何在PHP中获取最后创建的目录？

Question

Dynamically I am creating sub directory in a folder and I need to get the last created directory in a sting format, I have tried many ways but failed to get it. What i have tried is,

$path = "/path/to/my/dir";
$latest_ctime = 0;
$latest_filename = '';
$d = dir($path);
while (false !== ($entry = $d->read())) {
$filepath = "{$path}/{$entry}";
if (is_file($filepath) && filectime($filepath) > $latest_ctime) {
$latest_ctime = filectime($filepath);
$latest_filename = $entry;
 }
}

But it works for only file. Thanks in advance.

Try something like this:

$path = "/path/to/my/dir";
$latest_mtime = 0;
$latest_filename = '';
if ($handle = opendir($path)) {
    $blacklist = array('.', '..');
    while (false !== ($file = readdir($handle))) {
        if (!in_array($file, $blacklist)) {
            if (is_dir($file) && filemtime($file) > $latest_mtime) {
                $latest_mtime = filemtime($file);
                $latest_filename = $file;
            }
        }
    }
    closedir($handle);
}

Also, you can change the condition of the blacklist for:

if (!in_array($file, $blacklist) && substr($file, 0, 1) != ".") {

to exclude hidden directories (in unix-like sistems).
