统计目录文件大小的php函数
早上刚到公司,头告诉我,抓紧写一个小函数,用来统计指定目录中文件大小,我了个去,动手吧,还好有点小基础,一会就完工了,哈哈。代码在下面咯。

 
/**

 function dirsize($dir)
 {
   @$dh = opendir($dir);
   $size = 0;
   while ($file = @readdir($dh))
  {
    if ($file != "." and $file != "..")
   {
     $path = $dir."/".$file;
      if (is_dir($path))
     {
       $size += dirsize($path);
      }
     elseif (is_file($path))
     {
       $size += filesize($path);
      }
    }
   }
  @closedir($dh);
  return $size;
 }
//function end 

//eg:
 $dir_path = "./my_files";
 $dir_size = dirsize($dir_path);
 $dir_size = $dir_size/1024/1024;
 echo $dir_size."MB";
 ?>
Copy after login

这个函数可以递归遍历目录中的所有文件,并计算以MB为单位的文件总大小。
新手出招,大佬们见笑了。
