A recursion counts to the number of files in a specific directory.

Code:: // folder path end with '/' function directoryListCount($folderPath) { $num_files= 0; $dirStream = opendir($folderPath); if (!$dirStream) return -1; while ($file = readdir($dirStream)) { if ($file == '.' || $file == '..') continue; if (is_dir($folderPath. $file)){ $num_files+= directoryListCount($folderPath. $file . DIRECTORY_SEPARATOR); } else { $num_files++; } } closedir($dirStream); return $num_files; }
