zephir开发的扩展“wudimei框架”之数据库使用方法

很喜欢laravel，以前写了一个wudimei php (https://github.com/wudimeicom/wudimeiphp)，就是学习laravel的方法名、类名、连写。

现在用zephir写成扩展。把wudimei 框架编译成wudimei.so，复制到php7.2.3的安装目录。然后放在php.ini中。extension=wudimei.so

我使用的是ubuntu kylin 17.10 x86_64的操作系统。

使用该框架时，不需要require_once wudimei框架的php文件，因为它本身是扩展，没有相应的php文件。
