PHP积分兑换接口实例

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 id='{$user_id}' and answer_points>={$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 id='{$user_id}'");  

            }  

            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 id='{$user_id}'");  

            }  

            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();
