php语法如何实现内定抽奖功能？

<?php
$prize = [
    ['name' => 'iphone13', 'winners' => ['小米']],
    ['name' => '佳能相机', 'winners' => ['小木', '小明']],
    ['name' => '洗碗机', 'winners' => ['冬冬']],
    ['name' => '加班一天', 'winners' => ['小幻']],
    ['name' => 'VR眼镜', 'winners' => ['空空']]
];
  
// 冬冬开始抽奖
// 这里的用户也可以是用户唯一标识
$user = '冬冬';
  
$result = '谢谢参与';
foreach ($prize as $item) {
    if (in_array($user, $item['winners'])) {
        $result = $item['name'];
        break;
    }
}
  
print_r('获得的奖品：' . $result);
