我這里用的是thinkcmf5 column,toArray,這些是框架自帶的函數(shù)

```

<?php

//多條

//取出red_prize的ID并轉(zhuǎn)成一維數(shù)組

? $list = Db::name('red_prize')->column('id');

? //? $list = Db::name('red_prize')->select();

? //$list = array_column($list,'id');

? ? ? ? $rand_list = array_rand($list,3);//隨機(jī)抽取3條

? ? ? ? $tuijian_array = array();

? ? ? ? foreach ((array)$rand_list as $key) {

? ? ? ? ? ? $tuijian_array[] = $list[$key];

? ? ? ? }

? ? ? ? $randArr = Db::name('red_prize')->where('id','in',$rand_list)->select()->toArray();

```
