PHP转盘抽奖接口实例_php技巧

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：

<?php  <br />/*session_start(); <br />if(!isset($_SESSION['zaszh_user_id'])){ <br />    echo json_encode(array('status'=>'error','msg'=>'连接超时，请重新打开页面。')); <br />    exit; <br />} <br />$user_id = $_SESSION['zaszh_user_id'];*/  <br />  <br />$user_id = 1; // 测试用  <br />  <br />// 转盘区域  <br />$arr_area = array(  <br />    '0' => array('min_angle'=>1,'max_angle'=>45,'prize'=>'小米'),<br />    '1' => array('min_angle'=>46,'max_angle'=>90,'prize'=>'拍立得'),<br />    '2' => array('min_angle'=>91,'max_angle'=>135,'prize'=>'10元话费'), <br />    '3' => array('min_angle'=>136,'max_angle'=>180,'prize'=>'5元话费'), <br />    '4' => array('min_angle'=>181,'max_angle'=>225,'prize'=>'谢谢参与'),<br />    '5' => array('min_angle'=>226,'max_angle'=>270,'prize'=>'谢谢参与'),<br />    '6' => array('min_angle'=>271,'max_angle'=>315,'prize'=>'谢谢参与'),<br />    '7' => array('min_angle'=>316,'max_angle'=>360,'prize'=>'谢谢参与')  <br />);
