To connect to a MySQL server, PHP needs a set of MySQL functions called "MySQL extension". This extension may be part of the PHP distribution (compiled-in), otherwise it needs to be loaded dynamically. Its name is probably mysql.so or php_mysql.dll. phpMyAdmin tried to load the extension but failed.

在PHP。INI中
extension=php_mysql.dll
mysql.default_port =3306
mysql.default_socket =没有设置
mysql.default_host =localhost
mysql.default_user =root
mysql.default_password =*****
已经搞好但还是出了上边的问题
请指教
