我有这段代码，它的作用是知道我在表单中输入的那一天有多少人被预订。查询运行得很好，并返回预期的结果。问题是我想在选择的一个小时旁边显示这个结果。所以它不会显示出来。如果id result-date的div或者从不同的时间选项中选择出来，我会看到结果。如何在选项中查看查询结果？
这是check_availablity. php的文件。

require('config.php');

sleep(1);

$data = $_POST['data'];

$result = $connexion->query(
    'SELECT persones FROM reservas where data = \''.$data.'\' ORDER by hora ASC'
);

if ($result->num_rows > 0) {
    foreach ($result as $hores){
        echo $hores['persones'].' llocs disponibles.';
    }
}
else{
    echo 'Esta tot reservat';
}
