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"> <div id="view-login"> <present name="wxuser"> <div id="wxuser"> <div> <img src="{sh:$wxuser.headimgurl}"> </div> <h4>{sh:$wxuser.nickname}</h4> </div> </present> <> <div id="login"> <h4>登录</h4> <div>忘记密码</div> <form role="form" type="get"> <div> <label>手机号码</label> <input type="tel" name="tel" id="tel_num" placeholder="请输入手机号码" value=""> </div> <div> <label>登录密码</label> <input type="password" name="password" placeholder="请填写密码"> </div> <div></div> </form> <div> <button type="button">确认</button> </div> <div>免费注册</div> </div> <> <div id="register"> <h4>注册账号</h4> <form role="form"> <div> <label>手机号码</label> <input type="tel" name="tel" id="tel_num" placeholder="请输入手机号码" value=""> </div> <div> <label>验证码</label> <button type="button">获取验证码</button> <input type="text" placeholder="请填写验证码" name="smscode" /> </div> <div> <label>登录密码</label> <input type="password" placeholder="设置登录密码" name="password" maxlength="30"> </div> <div> <label>确认密码</label> <input type="password" placeholder="确认登录密码" name="re_password" maxlength="30"> </div> <div> </div> </form> <div> <button type="button">确认</button> </div> <div>立即登录</div> </div> <> <div id="changePwd"> <h4>修改密码</h4> <form role="form"> <div> <label>手机号码</label> <input type="tel" name="tel" id="tel_num" placeholder="请输入手机号码" value=""> </div> <div> <label>验证码</label> <button type="button">获取验证码</button> <input type="text" placeholder="请填写验证码" name="smscode" /> </div> <div> <label>新密码</label> <input type="password" placeholder="设置登录密码" name="password" maxlength="30"> </div> <div> <label>确认密码</label> <input type="password" placeholder="确认登录密码" name="re_password" maxlength="30"> </div> <div> </div> </form> <div> <button type="button">确认</button> </div> <div>立即登录</div> </div> </div> </div>

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。
希望本文所述对大家PHP程序设计有所帮助。
