php使用递归计算文件夹大小,

方法很简单,这里就不多废话了,直接奉上代码:

复制代码 代码如下:


protected function dir_size($dir){
        $dh = opendir($dir);             //打开目录,返回一个目录流
        $size = 0;      //初始大小为0
        while(false !== ($file = @readdir($dh))){     //循环读取目录下的文件
           if($file!='.' and $file!='..'){
            $path = $dir.'/'.$file;     //设置目录,用于含有子目录的情况
                if(is_dir($path)){
                $size += $this->dir_size($path);  //递归调用,计算目录大小
                }elseif(is_file($path)){
                    $size += filesize($path);   //计算文件大小
                }
            }
        }  
        closedir($dh);             //关闭目录流
        return $size;               //返回大小
    }
