PHP获取文件夹大小函数用法实例

   本文实例讲述了PHP获取文件夹大小函数用法。分享给大家供大家参考。具体如下:

  ?

  // 获取文件夹大小

  function getDirSize($dir)

  {

  $handle = opendir($dir);

  while (false!==($FolderOrFile = readdir($handle)))

  {

  if($FolderOrFile != "." && $FolderOrFile != "..")

  {

  if(is_dir("$dir/$FolderOrFile"))

  {

  $sizeResult += getDirSize("$dir/$FolderOrFile");

  }

  else

  {

  $sizeResult += filesize("$dir/$FolderOrFile");

  }

  }

  }

  closedir($handle);

  return $sizeResult;

  }

  // 单位自动转换函数

  function getRealSize($size)

  {

  $kb = 1024; // Kilobyte

  $mb = 1024 * $kb; // Megabyte

  $gb = 1024 * $mb; // Gigabyte

  $tb = 1024 * $gb; // Terabyte

  if($size

  {

  return $size." B";

  }

  else if($size

  {

  return round($size/$kb,2)." KB";

  }

  else if($size

  {

  return round($size/$mb,2)." MB";

  }

  else if($size

  {

  return round($size/$gb,2)." GB";

  }

  else

  {

  return round($size/$tb,2)." TB";

  }

  }

  echo getRealSize(getDirSize('需要获取大小的目录'));

  ?>
