laravel 4 启用firephp 支持
目前项目中选用的开发框架是laravel4,经过几天的阅读源码以及看社区教程,发现是比较先进和强大的框架.
?
只是对新手入门这块做的很不给力,虽然官方文档在中文化上比较完整,但是相应的文档都是浅尝辄止,项目中用到的东西讲到的都比较少....
?
为了方便开发测试,所以把firephp予以集成,具体读源码找文档的时间就不说了,大致如下,在 app/start/global.php 文件中加入行:
log::getmonolog()->pushhandler(new firephphandler(logger::debug));
?然后在代码中使用log类就能输出结果...
?
另外对其db查询器使用不是很赶趟,项目组中的妹子也不会用,所以我把aertdb单独领出来做成了插件形式...
