数据库数据表创建语法:
DROP TABLE IF EXISTS `admin`;
CREATE TABLE IF NOT EXISTS `admin`(
`adminid` INT UNSIGNED NOT NULL AUTO_INCREMENT COMMENT ‘主键ID‘,
`adminuser` VARCHAR(32) NOT NULL DEFAULT ‘‘ COMMENT ‘管理员账号‘,
`adminpass` CHAR(32) NOT NULL DEFAULT ‘‘ COMMENT ‘管理员密码‘,
`adminemail` VARCHAR(50) NOT NULL DEFAULT ‘‘ COMMENT ‘管理员电子邮箱‘,
`logintime` BIGINT UNSIGNED NOT NULL DEFAULT ‘0‘ COMMENT ‘登录时间‘,
`loginip` BIGINT NOT NULL DEFAULT ‘0‘ COMMENT ‘登录IP‘,
`createtime` INT UNSIGNED NOT NULL DEFAULT ‘0‘ COMMENT ‘创建时间‘,
PRIMARY KEY(`adminid`),
UNIQUE admin_adminuser_adminpass(`adminuser`, `adminpass`),
UNIQUE admin_adminuser_adminemail(`adminuser`, `adminemail`)
)ENGINE=InnoDB DEFAULT CHARSET=utf8;
(1)mysql控制台下:
ip地址转整型类型:inet_aton
mysql> update admin set userip=inet_aton(‘192.168.1.1‘) where username=‘admin‘;
mysql> select * from admin; +---------+-----------+----------------------------------+----------------+------------+------------+------------+ | adminid | adminuser | adminpass | adminemail | logintime | loginip | createtime | +---------+-----------+----------------------------------+----------------+------------+------------+------------+ | 1 | admin | 202cb962ac59075b964b07152d234b70 | zq@zqblogs.cn | 1482500788 | 3232235777 | 1482419387 | +---------+-----------+----------------------------------+----------------+------------+------------+------------+ 1 row in set (0.00 sec)
整型转ip地址类型:inet_ntoa
mysql> select inet_ntoa(4294967295);
+-----------------------+ | inet_ntoa(4294967295) | +-----------------------+ | 255.255.255.255 | +-----------------------+
(2)php代码实现:ip2long
通过php代码将ip地址插入到数据类型为int或bigint的字段中(使用yii框架的语法)
$this->updateAll(
[‘logintime‘ => time(), ‘loginip‘ => ip2long(Yii::$app->request->userIP)],
‘adminuser = :user‘,
[‘:user‘ => $this->adminuser]
);
Yii::$app->request->userIP:表示通过http请求头获取到当前用户浏览器的ip地址(注:可通过$_SERVER[‘REMOTE_ADDR‘]获取到本地ip地址)
(说明1:使用127.0.0.1访问本地apache服务器,而不要用localhost,localhost对应的ip为::1,不符合数据库限制的bigint类型)
(说明2:关于web服务器的ip地址和域名映射关系是在C:\Windows\System32\drivers\etc\hosts文件中配置的
)
