求PHP脚本检测MYSQL 字符集和端口
求PHP脚本检测MYSQL 字符集和端口 在线等

------解决方案--------------------
端口：show variables like 'port';

字符集： SHOW VARIABLES LIKE 'character%' 

在用php输出即可。
------解决方案--------------------
端口能检测出来吗？
虽然 show variables like 'port'
得到的是端口，但他必须在连接到数据库以后才可以执行
而不知道端口时，是不能连接到数据库的
除非你依次尝试，遍历整个可能的端口号，直到找到数据库服务为止
