将第二个查询结果作为关联数组推送到从fetch_assoc获取的现有数据中

$query1 = "SELECT * FROM table1";
$result1 = mysqli_query($connection, $query1);

$data = array();
while ($row = mysqli_fetch_assoc($result1)) {
    $data[] = $row;
}

$query2 = "SELECT * FROM table2";
$result2 = mysqli_query($connection, $query2);

while ($row = mysqli_fetch_assoc($result2)) {
    $data[] = $row;
}
