php面试上机题（2018-3-3）

需求：将第三方api的前3000条数据全部读取出来，存入对应的数据库字段

第三方api：http://pub.cloudmob.mobi/publisherapi/offers/?uid=92&key=d4bab08884781dbf2bede528e27d243d&limit=1000&page=1

sql代码：

/*

DROP TABLE IF EXISTS `offers`;
CREATE TABLE `offers` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,

php代码：

 <?php
 //思路：
 // 1.先通过php的curl将数据取出来，转换为对象
 // 2.连接数据库，做预处理
 // 3.将取出来的值转换为数组，并绑定数据库参数
 // 4.执行sql操作，数据抓取成功
 //ps：数据的初始化及url会话的关闭只能执行一次，所以放在for循环的后面
