sql关联数组，列名为标题

Question

我的数据库中有一个简单的表，其中包含来自用户和来自用户的消息。现在有一个来自用户，另一个来自用户。我想用fromUser组织我的结果，其中包含所有行数据：

Array(
  user1 => array(array(
    [id] => 1
    [message] => some message from user 1
    ),
    (
    [id] => 1
    [message] => another message from user 1
    )),
  user2 => array(array(
    [id] => 2
    [message] => some message from user 2
    ),
    (
    [id] => 2
    [message] => another message from user 2
    )),
  user3 => array(array(...

我知道我的语法可能不对，但我希望你明白我的观点。我尝试使用＆＃34; group by fromName＆＃34;但那只给了我最后的信息。这样的查询的正确语法是什么？

$query = mysqli_query($link, "SELECT * FROM messages WHERE toName='$to' group by fromName");
$messages = array();
while ($row = mysqli_fetch_assoc($query)) {
    $messages[] = $row; //or
    $messages[$row['fromName']] = $row; //didn't work either
}
print_r($messages);

修改：刚刚找到了令人毛骨悚然的答案：

$query = mysqli_query($link, "SELECT * FROM messages WHERE toName='$to'");
$messages = array();
while ($row = mysqli_fetch_assoc($query)) {
    $messages[$row['fromName']][] = $row;
}
print_r($messages);

猜猜你只需要从＆＃34; $messages[$row['fromName']->[]<-＆＃34;制作数组。
