Do the almighty gods have any better lottery algorithm?

return false

This is what I wrote before. There are two popular algorithms used on the Internet, and the probability is too high. I had to go back to the textbook and just put all the winning balls and interference balls into the basket and draw them randomly.
And the lottery is drawn directly without putting it back. We only need to give out the prizes again and if the prizes are gone, we will directly give out the prizes as a thank you for participating.

                array('id'=>1,'name'=>'苹果电脑','chance'=>1),
                array('id'=>2,'name'=>'苹果手机','chance'=>2),
                array('id'=>3,'name'=>'1000元购物卡','chance'=>3),
                array('id'=>4,'name'=>'300元餐具','chance'=>4),

This problem is relatively easy to solve. Assume there are 100 prizes and 100 people to whom they are distributed. The 100 prizes are numbered as award0-99, and the 100 people to whom they are distributed are numbered as person0-99. The code is implemented as follows:

<code><?php
/**
 * 关注微信公众号：phpgod.
 * User: PHP技术大全
 * Date: 2016/10/9
 * Time: 9:47
 */
$list = range(0,99);
$awardList = $list;
$personList = $list;
shuffle($awardList);
shuffle($personList);

$targetAwardResult = array_combine($awardList,$personList);

var_export($targetAwardResult);</code>
