这篇文章主要介绍了PHP实现的登录，注册及密码修改功能,结合实例形式分析了php实现登陆功能的相关数据库操作、ajax交互、数据验证及验证码相关操作技巧,需要的朋友可以参考下

这里介绍注册，登录，修改密码的界面布局与功能实现：

1.登录

2.忘记密码

3.免费注册

页面布局：

<p id="views" class="views">
  <p id="view-login" class="page-view view-login active">
    <present name="wxuser">
      <p id="wxuser" class="form-group text-center">

          <img src="{sh:$wxuser.headimgurl}">
        </p>
        <h4 class="nickname">{sh:$wxuser.nickname}</h4>
      </p>
    </present>

小结：

1.注册与修改密码用到了短信验证。
2.安全起见，前端ajax验证。后端亦进行验证。
3.流程合理，切换自如。
4.功能全面，登录，注册，密码修改齐全。

以上就是本文的全部内容，希望对大家的学习有所帮助。
