 更新時間：2016年11月25日 14:46:16   作者：牛逼的霍嘯林  
這篇文章主要介紹了PHP實現(xiàn)的登錄，注冊及密碼修改功能,結(jié)合實例形式分析了php實現(xiàn)登陸功能的相關(guān)數(shù)據(jù)庫操作、ajax交互、數(shù)據(jù)驗證及驗證碼相關(guān)操作技巧,需要的朋友可以參考下

本文實例講述了PHP實現(xiàn)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：

這里介紹注冊，登錄，修改密碼的界面布局與功能實現(xiàn)：

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>

    </present>

小結(jié)：

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。后端亦進行驗證。
3.流程合理，切換自如。
4.功能全面，登錄，注冊，密碼修改齊全。
