ThinkPHP3.2.3学习笔记4---统计ThinkPHP3.2.3加载的文件

将ThinkPHP3.2.3的入口文件index.php加入一个函数getIncludeFiles，文件内容变成如下所示:

1 <?php

12 // 应用入口文件

14 // 检测PHP环境
15 if(version_compare(PHP_VERSION,'5.3.0','<'))  die('require PHP > 5.3.0 !');
16 
17 // 开启调试模式 建议开发阶段开启 部署阶段注释或者设为false
18 define('APP_DEBUG',True);
19 
20 // 定义应用目录
21 define('APP_PATH','./Application/');
22 
23 // 引入ThinkPHP入口文件
24 require './ThinkPHP/ThinkPHP.php';
25 
26 // 亲^_^ 后面不需要任何代码了 就是如此简单

28 getIncludeFiles();
29 
30 function getIncludeFiles() {
31     $files = get_included_files();
32 
33     $fileCount = count($files);
34     echo "ThinkPHP3.2.3框架共加载{$fileCount}个文件<br />\n";
35     $i = 0;
36     foreach ($files as $file) {
37         $i++;
38         echo "{$i}、Included file {$file}...<br />\n";
39     }
40 }
41 ?>      

在浏览中访问http://localhost:81/research/thinkphp_3.2.3_full/index.php

输出如下：

ThinkPHP3.2.3框架共加载27个文件

总结：

只是访问入口文件index.php，没有完成任何功能，就加载了27个文件，如果要调用具体的业务逻辑加载的文件还会更多，而且业务中可能还会调用数据库、NoSQL、文件系统、消息队列等系统，一个请求从开始到结束的时间可能会更长。

对于高并发、高可用、高性能的分布式系统来说，性能显得尤为重要，使用框架可能会提高开发效率，但是对性能可能会有一些影响，所以有些大公司采用自己写的框架或不用框架来开发项目。
