php.ini扩展开了，为什么找不到mysql模块，无法连接mysql啊

如题

mysql也是可以连接的

mysql> use testDatabase changedmysql> source e:/sql/DB.SQL;Query OK, 0 rows affected (0.03 sec)

php.ini里也打开了

phpinfo();显示里 只有mysqld：

回复讨论(解决方案)

extension=php_mysqli.dll

试了，也没用，全部扩展都打开还是不行。。。

phpinfo();同时也显示了使用的php.ini在哪里
请检查是否与你修改的一致

将PHP目录下的libmysql.dll拷入system32目录，如是64位系统，则拷入syswow64目录
