hi what is folderSize($each); I think this one should be undefined

@sakonachhoeurng Hi, you probably noticed already) but just in case, It's the function name - recursive call, to count all subfolders as fell.

Nice, however, at least on Linux, it won't include dot-files (since * does not match .some-file). Furthermore, on my machine an empty directory still occupies some space (4096 bytes according to du), this is also not included in folderSize.

Oh, and thanks, I'm using something very similar.

For directory size:
if($size<1024){$size=$size." Bytes";}
elseif(($size<1048576)&&($size>1023)){$size=round($size/1024, 1)." KB";}
elseif(($size<1073741824)&&($size>1048575)){$size=round($size/1048576, 1)." MB";}
else{$size=round($size/1073741824, 1)." GB";}
return $size;

Nice but nothing beats the Swag of the following when the directory size is large.

    $f = './path/directory';
    $io = popen ( '/usr/bin/du -sk ' . $f, 'r' );
    $size = fgets ( $io, 4096);
    $size = substr ( $size, 0, strpos ( $size, "\t" ) );
    pclose ( $io );
    echo 'Directory: ' . $f . ' => Size: ' . $size;

This function converts bytes:

function sizeFilter($bytes)
    {
        $label = array('B', 'KB', 'MB', 'GB', 'TB', 'PB');

        for ($i = 0; $bytes >= 1024 && $i < (count($label) - 1); $bytes /= 1024, $i++) ;

        return (round($bytes, 2) . " " . $label[$i]);
    }

-h, --human-readable print sizes in human readable format (e.g., 1K 234M 2G)

    $f = './path/directory';
    $io = popen ( '/usr/bin/du -sh ' . $f, 'r' );
    $size = fgets ( $io, 4096);
    $size = substr ( $size, 0, strpos ( $size, "\t" ) );
    pclose ( $io );
    echo 'Directory: ' . $f . ' => Size: ' . $size;

In GigaBytes:

return $size / 1e-9; //GigaBytes
