注： Ecstore是一款企业级B2C电子商城系统，与Ecshop一样同出商派。
写了这么多年代码，如果有人问你，你的项目有多少个文件、多少行代码、多少个方法，你可以用确切的数据回答他吗？
当项目经理、产品经理给你安排一个他们觉得非常简单的需求时，你可以用确切的数据告诉他这有多复杂吗？
下面给你介绍一个代码复杂度检测工具：PHPLOC
[lru @ bin]$./phploc ~/project/b2c/ecstore

以上就是phploc 检测 ecstore v2.3.80的代码情况。可以看出来：
- ecstore有** 995 **个php目录
- ecstore有** 2515 **个php文件
- ecstore有** 340269 **行php代码
...
PHPLOC的安装非常简单：
$ wget https://phar.phpunit.de/phploc.phar
$ php56 phploc.phar
$ composer require --dev phploc/phploc
$ cd vendor/bin/
$ ./phploc ~/project/b2c/ecstore
** 注： **当然还有别的工具，如：phpmetrics，请自行谷歌。
