can you post your code for the number of files, so we can just build on it?

 $path = 'folder/';
print count(glob($path . '*.*'))

simple as that :)

well, I can't build on that, I was thinking you were outputting the name of each file in the folder.
Try this, there are two functions, one returns the size of the folder, and the other makes the answer readable, instead of something like 322993445 bytes, it gives the answers in appropriate units, kb, mb, etc
function foldersize($path) {
    $total_size = 0;
    $files = scandir($path);
    foreach($files as $t) {
        if (is_dir($t)) { // In case of folder
            if ($t<>"." && $t<>"..") { // Exclude self and parent folder
                $size = foldersize($path . "/" . $t);
                // print("Dir - $path/$t = $size<br>\n");
                $total_size += $size;
        else { // In case of file
            $size = filesize($path . "/" . $t);
            // print("File - $path/$t = $size<br>\n");
            $total_size += $size;
    return $total_size;
function size_readable ($size, $retstring = null) {
        // gives folder size in a readable way
        $sizes = array('B', 'kB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB');
        if ($retstring === null) { $retstring = '%01.2f %s'; }
        $lastsizestring = end($sizes);
        foreach ($sizes as $sizestring) {
                if ($size < 1024) { break; }
                if ($sizestring != $lastsizestring) { $size /= 1024; }
        if ($sizestring == $sizes[0]) { $retstring = '%01d %s'; } // Bytes aren't normally fractional
        return sprintf($retstring, $size, $sizestring);
 $totalfoldersize = foldersize('put the actual path to the folder in here');
 $results = size_readable($totalfoldersize);
 echo $results;
