用Simplepie解析爱范的源时，出现如下错误：http://www.ifanr.com/feed is invalid XML, likely due to invalid characters. XML error: Invalid character at line 604, column 37，比较麻烦。
最后在Simplepie的代码的1397行里加入：
XML/HTML代码
- $this->raw_data = preg_replace('/[^\P{C}\n]+/u','',$this->raw_data);
说实在的，这种不可见的字符最TMD恶心了！~
因为用了pjax，所以URL在请求的时候都是被自动加了?pjax-container=xxxxx，但请求完pjax后，location的pushState又会去掉这个pjax-container。所以要解决签名问题，其实就是在签名的时候把pjax-container去掉
因此jssdk()->config(xxx)的时候，先在前面加入jssdk()->setUrl(Url::to([''],true))->config('')...问题解决！
就是这么简单！
不多说上图

因为在框架里面，所以include_files就这么多（没办法，没开始opcache）
前5条是用的localhost后5条是127.0.0.1，瞅瞅，就是这样的区别！
先说再写：
全局更新
- composer global require hirak/prestissimo
即使你用了这玩意，还是得先用国内的源，否则所谓的加速也是白搭。
GITHUB在这里：https://github.com/hirak/prestissimo
看官网的介绍，提升有10倍，虽然 我们在国内没有这么高的提速，但感觉上还是快了不少（应该不是安慰剂）
mysql在升到php7后，原有的mysql_*函数都没有了，如果要迁移，可以参考 这一篇：https://stackoverflow.com/questions/36073703/mysql-to-pdo-comparison-table
介绍的比较详细，比如mysql常用的几个函数的转换写法，这里都有了：
随便截一点内容，详细的还是去网站看：

MySQL_ Original Driver to PDO Comparative Table
Introduction:
This table is not intended to be a tutorial or a guide to PDO, but to provide a correspondence between MySQL_ and PDO. So, some important PDO commands are missing, if they don't have a MySQL_ correspondence.
Among these omitted commands, there is a major PDO feature, the prepared statements. I strongly recommend to use it, also if only cited in this guide.
This is a very extended answer. I'm sorry for the low quality of spelling (I'm not english) and for the typos. I will try to correct and improve it in the next few days. Any suggestion or contribution is welcome.
Naming Conventions:
To avoid misunderstanding, in this answer I use:
In PDO, we have two major object types, the PDOObject (the connection between PHP and a database server) and the PDOStatement (a prepared statement and, after the statement is executed, an associated result set). In this answer, variable names are:
$dbh, refer to PDOobject;$stmt, refer to PDOStatement.
