本文实例讲述了PHP实现登录，注册及密码修改功能的方法。分享给大家供大家参考，具体如下：
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：
<div id="views" class="views">
<div id="view-login" class="page-view view-login active">
<present name="wxuser">
<div id="wxuser" class="form-group text-center">

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