想了解PHP转盘抽奖接口实例的相关内容吗,yhb241在本文为您仔细讲解PHP转盘抽奖接口的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:PHP,转盘,抽奖,接口,下面大家一起来学习吧。

本文实例讲述了PHP转盘抽奖接口的实现方法。分享给大家供大家参考。具体如下:

这里的转盘抽奖随机返回一个转盘角度,概率可自己定义

lottery_get.php接口文件如下:

复制代码 代码如下:
<?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 
 
// 转盘区域 
$arr_area = array( 
    '0' => array('min_angle'=>1,'max_angle'=>45,'prize'=>'小米'),
    '1' => array('min_angle'=>46,'max_angle'=>90,'prize'=>'拍立得'),
    '2' => array('min_angle'=>91,'max_angle'=>135,'prize'=>'10元话费'),
    '3' => array('min_angle'=>136,'max_angle'=>180,'prize'=>'5元话费'),
    '4' => array('min_angle'=>181,'max_angle'=>225,'prize'=>'谢谢参与'),
    '5' => array('min_angle'=>226,'max_angle'=>270,'prize'=>'谢谢参与'),
    '6' => array('min_angle'=>271,'max_angle'=>315,'prize'=>'谢谢参与'),
