PHP积分兑换接口实例
这篇文章主要介绍了PHP积分兑换接口,实例分析了积分兑换接口的逻辑处理与数据库操作技巧,需要的朋友可以参考下
本文实例讲述了PHP积分兑换接口的实现方法。分享给大家供大家参考。具体实现方法如下:
exchange.php接口内容如下:
- <?php
- /*session_start();
- if(!isset($_SESSION['zaszh_user_id'])){
- echo json_encode(array('status'=>'error','msg'=>'连接超时,请重新打开页面。'));
- exit;
- }
- $user_id = $_SESSION['zaszh_user_id'];*/
- $user_id = 1; // 测试用
- $exchange_points = intval($_GET['exchange_points']);
- require('connect_database.php');
- // 扣除答题积分
- $mysqli->query("update zaszh_user set answer_points=answer_points-{$exchange_points} where and answer_points>={$exchange_points}");
- if($mysqli->affected_rows){
- // 有积分
- switch($exchange_points){
- // 5元话费
- case 200:
- $mysqli->query("update zaszh_telephone_charge_surplus set charge_surplus=charge_surplus-5 where date=substring(now(),1,10) and charge_surplus>=5");
- if($mysqli->affected_rows){
- // 有剩余
- $mysqli->query("insert into zaszh_award(user_id,prize,create_date) values('{$user_id}','5元话费',unix_timestamp(now()))");
- if($mysqli->affected_rows){
- echo json_encode(array('status'=>'success','msg'=>'5元话费'));
- }else{
- // 获奖失败
- }
- }else{
- // 无剩余
- // 恢复答题积分
- $mysqli->query("update zaszh_user set answer_points=answer_points+{$exchange_points} where ");
- }
- break;
- // 10元话费
- case 400:
- $mysqli->query("update zaszh_telephone_charge_surplus set charge_surplus=charge_surplus-10 where date=substring(now(),1,10) and charge_surplus>=10");
- if($mysqli->affected_rows){
- // 有剩余
- $mysqli->query("insert into zaszh_award(user_id,prize,create_date) values('{$user_id}','10元话费',unix_timestamp(now()))");
- if($mysqli->affected_rows){
- echo json_encode(array('status'=>'success','msg'=>'10元话费'));
- }else{
- // 获奖失败
- }
- }else{
- // 无剩余
- // 恢复答题积分
- $mysqli->query("update zaszh_user set answer_points=answer_points+{$exchange_points} where ");
- }
- break;
- }
- // 记录积分消耗
- $mysqli->query("insert into zaszh_answer_points_consume(user_id,points_consume,consume_for,create_date) values('{$user_id}','{$exchange_points}','exchange',unix_timestamp(now()))");
- }else{
- // 无积分
- echo json_encode(array('status'=>'error','msg'=>'您的积分不足。'));
- }
- $mysqli->close();
