统计目录下文件数及大小

 1 private function getFileCacheCount($pathName)
 2 {
 3   $data = [
 4 
 5     //文件的个数
 6     'num' => 0,
 7 
 8     //文件的大小
 9     'size' => 0
10   ];
11 
12   //打开目录
13   $dir = opendir($pathName);
14   while(false !== ($file_name = readdir($dir))){
15 
16     //去掉"."和".."
17     if(!($file_name == "." || $file_name == "..")){
18 
19       //拼接文件路径
20       $fileName = $pathName . "/" . $file_name;
21       if(is_dir($fileName)){
22 
23         //递归循环
24         $subData = $this->getFileCacheCount($fileName);
25         $data['size'] += $subData['size'];
26         $data['num'] += $subData['num'];
27       }else{
28         $data['size'] += filesize($fileName);
29         $data['num']++;
30       }
31     }
