php和mysql搜索用户

Question

我写这段代码是为了从 mysql 中搜索用户:

$query = $db->query("SELECT * FROM `users` WHERE `id` = {$id} ");
while($row = $query->fetch_assoc()){
    echo $row['username'];
    // ....
    echo "People also search :";
    // the people also search box
}

我想要这样当用户页面在页面底部加载时是这样的框:

沃尔特

...

人们也在搜索:

布鲁斯 凯文 杰西

当你搜索 Actor 或......时，就像谷歌一样

我该怎么做？

你为什么不先让它与数据库响应中的一些随机值一起工作

$query = $db->query("SELECT username FROM `users");
while($row = $query->fetch_assoc()){
     $rows[]=$row
}
//id of the user by which you have made the search
echo $rows[$id];
unset($rows[$id]);
echo "People also search :".PHP_EOL;
$rand_keys = array_rand($rows, 5);
foreach($rand_keys as $key){
    echo $rows[$key];
}
