PHP積分兌換接口實例，php積分兌換實例

本文實例講述了PHP積分兌換接口的實現方法。分享給大家供大家參考。具體實現方法如下：

exchange.php接口內容如下：

復制代碼 代碼如下:<?php 
 
/*session_start();
if(!isset($_SESSION['zaszh_user_id'])){
    echo json_encode(array('status'=>'error','msg'=>'連接超時，請重新打開頁面。'));
    exit;
}
$user_id = $_SESSION['zaszh_user_id'];*/ 
 
$user_id = 1; // 測試用 
$exchange_points = intval($_GET['exchange_points']); 
 
require('connect_database.php'); 
// 扣除答題積分 
$mysqli->query("update zaszh_user set answer_points=answer_points-{$exchange_points} where id='{$user_id}' and answer_points>={$exchange_points}"); 
if($mysqli->affected_rows){ 
    // 有積分 
    switch($exchange_points){ 
        // 5元話費 
        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元話費',unix_timestamp(now()))"); 
                if($mysqli->affected_rows){ 
                    echo json_encode(array('status'=>'success','msg'=>'5元話費')); 
                }else{ 
                    // 獲獎失敗 
                } 
            }else{ 
                // 無剩余 
                // 恢復答題積分 
                $mysqli->query("update zaszh_user set answer_points=answer_points+{$exchange_points} where id='{$user_id}'"); 
            } 
            break; 
        // 10元話費 
        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元話費',unix_timestamp(now()))"); 
                if($mysqli->affected_rows){ 
                    echo json_encode(array('status'=>'success','msg'=>'10元話費')); 
                }else{ 
                    // 獲獎失敗 
                } 
            }else{ 
                // 無剩余 
                // 恢復答題積分 
                $mysqli->query("update zaszh_user set answer_points=answer_points+{$exchange_points} where id='{$user_id}'"); 
            } 
            break; 
    } 
 
    // 記錄積分消耗 
    $mysqli->query("insert into zaszh_answer_points_consume(user_id,points_consume,consume_for,create_date) values('{$user_id}','{$exchange_points}','exchange',unix_timestamp(now()))"); 
}else{ 
    // 無積分 
    echo json_encode(array('status'=>'error','msg'=>'您的積分不足。')); 
} 
$mysqli->close();
