一个写了七年PHP代码的码农，写出来的代码就这个水平，说实在，自个儿都看不下去了。
偶尔撸别人的源码，优雅，思路清晰，边界判断逻辑严密，一万个羡慕嫉妒恨。可是这种好代码该如何才能写的出来呢。
你瞧别人写个代码基本不用怎么测试，交付就等于验收，没有什么一次回归二次回归。
曾经比较火的一款PHP博客程序Emlog也宣布要关闭论坛了，互联网变化太快，曾经写博客的都放弃了或者转自媒体平台了，那些独立博客程序也越来越少人使用。
我曾经使用过pjblog、z-blog、bo-blog、sablog、WordPress等开源博客程序，也开发过几款WordPress插件，后来自己开发博客程序自己用。在这移动互联网时代了，写博客确实过时了，写了没人看，搜索引擎也给不了多少个流量，写来写去变成了一个个人日记本。还不如搞个公众号，或者自媒体上发点动态，有人评论互动才有意义，你觉得呢？
