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

;;extension=php_bz2.dll;extension=php_curl.dll;extension=php_fileinfo.dllextension=php_gd2.dll;extension=php_gettext.dll;extension=php_gmp.dll;extension=php_intl.dll;extension=php_imap.dll;extension=php_interbase.dll;extension=php_ldap.dllextension=php_mbstring.dll;extension=php_exif.dll      ; Must be after mbstring as it depends on itextension=php_mysql.dll;extension=php_mysqli.dll;extension=php_oci8.dll      ; Use with Oracle 10gR2 Instant Client;extension=php_oci8_11g.dll  ; Use with Oracle 11gR2 Instant Client;extension=php_openssl.dll;extension=php_pdo_firebird.dllextension=php_pdo_mysql.dll;extension=php_pdo_oci.dll;extension=php_pdo_odbc.dll;extension=php_pdo_pgsql.dll;extension=php_pdo_sqlite.dll;extension=php_pgsql.dll;extension=php_pspell.dll;extension=php_shmop.dll

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
