PHP实现的登录，注册及密码修改功能分析

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">

   $req->setSmsType("normal");
   $req->setSmsFreeSignName("变更验证"); //短信签名固定，不可以换其他字
   $req->setSmsParam("{"code":"". $smscode ."","product":"【多多助店宝】"}");
   $req->setRecNum("{$tel}");
   $req->setSmsTemplateCode("SMS_5056861");
   $resp = $c->execute($req);
   if(!$resp->code) {
    //设置发送限制时间
    session($this->smstime, time() + 50);
    //设置验证码5分钟内有效
    session($this->smscode, array("code" => $smscode, "time" => time() + 600));
   } else {
    //发送失败写入日志文件
    $log = date("Y-m-d H:i:s") . " 发送失败 sub_code：{$resp->sub_code} sub_msg：{$resp->sub_msg}" . PHP_EOL;
    file_put_contents(RUNTIME_PATH . "Log/smscode.log", $log, FILE_APPEND);
   }
   $this->ajaxReturn(array("result" => !$resp->code));
  } else {
   $this->ajaxReturn(array("result" => false, "error" => "错误的请求"));
  }
}

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。
