Get Folder or Directory size in PHP

In PHP we have an inbuilt function called filesize() to get the size of any file, but what about a directory/ folder. A folder can content many files and sub folders in it. So lets write down a simple PHP function to calculate the folder size.

function folderSize($dir){
$count_size = 0;
$count = 0;
$dir_array = scandir($dir);
  foreach($dir_array as $key=>$filename){
    if($filename!=".." && $filename!="."){
          $new_foldersize = foldersize($dir."/".$filename);
          $count_size = $count_size+ $new_foldersize;
        }else if(is_file($dir."/".$filename)){
          $count_size = $count_size + filesize($dir."/".$filename);
return $count_size;

Call the function:

  $folder_name = "myFolder";
  echo folderSize($folder_name);

In the future i will make more statics of what a player has done but for now this is the result.
