php实现分页功能跳转和ajax方式实现

实现效果 

准备工作 

创建数据表和导入测试数据

CREATE TABLE `users` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `username` varchar(30) DEFAULT NULL COMMENT '账号',
  `email` varchar(30) DEFAULT NULL COMMENT '密码',
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

INSERT INTO `users` VALUES ('1', 'admin', '[email protected]');

INSERT INTO `users` VALUES ('2', 'xiaoming', '[email protected]');

INSERT INTO `users` VALUES ('3', 'xiaoming1', '[email protected]');

INSERT INTO `users` VALUES ('4', 'xiaoming2', '[email protected]');

INSERT INTO `users` VALUES ('5', 'xiaoming3', '[email protected]');

INSERT INTO `users` VALUES ('6', 'xiaoming4', '[email protected]');

INSERT INTO `users` VALUES ('7', 'xiaoming5', '[email protected]');

INSERT INTO `users` VALUES ('8', 'xiaoming6', '[email protected]');

INSERT INTO `users` VALUES ('9', 'xiaoming7', '[email protected]');
