Answer 1

PHP的版本？由于“不推荐”消息和最后一个“致命”错误，我在这里假设7.x（可能）。

这是一个两部分的事情...

1. 的弃用：

   PHP已经进行了更改使用__construct() （两个前导下划线）作为构造函数，而不是具有相同名称的班级本身。有关更多信息，请参阅PHP 4 style constructors部分（页面上的第一部分）。

   例如：在文件ADOConnection has a deprecated constructor...构造可能是这样的：

   ADOConnection(...); // constructors with or without parameters 
   

   ......但所有这些都可以被替换为：

   __construct(...); 
   

   可以做出的改变在本地解决已弃用的消息。

2. 致命错误：

   使用PHP 7.x中，该mysql_ *基于功能 删除。见this API info。
