现在想对PHP连接mysql的代码做try,catch处理.
应该怎么做,当出现连接数据库失败的时候,返回一串自定义的内容. 

try {				$this->conn = new mysqli('192.168.1.101','root','root11','testdb1');			}catch(Exception $e)		    {		    return $e->getMessage();		    }
Copy after login


回复讨论(解决方案)

mysqli_connect_errno() 或者 mysqli_connect_error()  不能满足你嘛？

得看是数据库安装设置的问题还是数据库设计的问题，mysqli_connect_errno() 能用来看数据库状态对不对的。
