Show oldest Folder

[Warlock]

Found a code to show oldest folder,but for some reason it shows only some weird dump,when tried output with echo nothing happening.Code is similar to function fo recursive scan for specific type of files which works fine but not sure what i missed here.

$dir="/path/";
function foldermtime($dir) {
    $foldermtime = 0;

$flags = FilesystemIterator::SKIP_DOTS | FilesystemIterator::CURRENT_AS_FILEINFO;
$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir, $flags));

while ($it->valid()) {
    if (($filemtime = $it->current()->getMTime()) > $foldermtime) {
        $foldermtime = $filemtime;
    }
    $it->next();
}

return $foldermtime ?: false;
}

var_dump(foldermtime(__DIR__));

This should work:

<?php

if ($handle = opendir('.\\')) {

//skip . and ...
   readdir($handle);
   readdir($handle);

$oldest_name=null;
$oldest_time=null;

//find the first directory
while (false !== ($file = readdir($handle)))  
    if(!is_file($file))
	{
		$oldest_name= $file; 
		$oldes_time = filemtime($file);
		break;
	}

//compare with the rest
	//find the first directory
    while (false !== ($file = readdir($handle)))  

        if(!is_file($file))
			if(filemtime($file)<$oldest_time)//if older than current
				$oldest_name=$file;			
 //output 
	if($oldest_name!=null)
		echo $oldest_name ;
	else
		echo 'No folder found.';
    closedir($handle);
}
?>
