This article describes how PHP calculates the entire directory size, in the following ways:

') continue;     Go recursive down, or add the file size    if (Is_dir ($DirectoryPath. $File))            $Size + = Calcdirectorysize ($Direc Torypath. $File. Directory_separator);    else       $Size + = FileSize ($DirectoryPath. $File);      }  Closedir ($Dir);  return $Size;} Example of use: $SizeInBytes = calcdirectorysize (' data/');
