本文實例講述了PHP實現登錄，注冊及密碼修改功能的方法。分享給大家供大家參考，具體如下：
這裡介紹注冊，登錄，修改密碼的界面布局與功能實現：
1.登錄
2.忘記密碼
3.免費注冊
頁面布局：
<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">
<div>
<img src="{sh:$wxuser.headimgurl}">
</div>
<h4 class="nickname">{sh:$wxuser.nickname}</h4>
</div>
</present>
<!--登錄-->

小結：
1.注冊與修改密碼用到了短信驗證。
2.安全起見，前端ajax驗證。後端亦進行驗證。
3.流程合理，切換自如。
4.功能全面，登錄，注冊，密碼修改齊全。
