php操纵mysqli数据库的实现方法

./configure --with-mysql=/usr/bin/mysql_config / #使用 Mysql ClientLibrary（libmysql）构建--with-mysqli=mysqlnd / #使用 Mysql Native Dirver 即mysqlnd--with-pdo-mysql=mysqlnd #使用 Mysql Native Dirver 即mysqlnd

./configure --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd 加上你的参数
