First of all, welcome to StackOverflow!. Read FAQ to help you interact with this Q/A site.

Now, let's move to the question. If I understand your question correctly (which is quite hard, given the sparse information you gave to us), you want to display 5 subfolder from certain folder.

It's quite simple, you can use a combination of DirectoryIterator, array, and krsort for that. Here's the example:

<?php
header('Content-Type: Text/Plain');
$dir = "d:/";

$iterator = new DirectoryIterator($dir);
$filenames = array();
foreach ($iterator as $fileinfo) {
    if ( !$fileinfo->isFile() ) {
        $filenames[$fileinfo->getMTime()] = $fileinfo->getFilename();
    }
}

print_r($filenames);

krsort($filenames);

print_r($filenames);

$maxDisplay = count( $filenames ) < 5 ? count( $filenames ) : 5;

$count=0;
foreach( $filenames  as $timestamp => $filename ) {
    $count++;
    echo "{$count}. {$filename}\n";
    if( $count == $maxDisplay) {
        break;
    }
}
