Question

我正在研究一个laravel应用程序，我正在尝试从eloquent从数据库返回的对象创建一个数组。对象看起来像这样，

        [
      {
        "id": 3,
        "body": "Fake User created the project Fake Project 2",
        "uri": "8jss90xk",
        "object_id": 422,
        "user": [
          {
            "id": 25,

        }
      }
}]

基本上，查询会返回所有未读通知的用户，我想将其与任何通知一起构建到数组中并发送电子邮件，但数组需要非常具体，包含其中包含的详细信息。

我想将这样的内容发送到将发送提醒的邮件功能

'user@emailaddress.com' => array(
   'first_name' => 'User',
   'last_name'  => 'Lastname',
   'projects' => array(
       'Project Title 1' => array(
         'notifications' => array(
            [0] => 'Notification 1',
            [1] => 'Notification 2',
            [2] => 'Notification 3'
         )
       )
   )
)

我不能为我的生活找出如何从我的对象构建这个数组，我目前在我的代码中有这个，

foreach($unread as $object) {
    $emails_to_send = array(
        'user' => $object->user[0],
        'uri' => $object->uri,
        'body' => $object->body,
        'project' => $object->project
    );
}

然而，这会构建错误的结构并覆盖最后一个循环。

Answer 1

在最后一个循环中获取数据的原因是因为您将新创建的数组分配给 $ emails_to_send 变量而不是附加到数组。请尝试以下方法：

$emails_to_send = array();

foreach($unread as $object) {
  $emails_to_send[] = array(
    'user' => $object->user[0],
    'uri' => $object->uri,
    'body' => $object->body,
    'project' => $object->project
  );
}

var_dump($emails_to_send);

这应该为您提供一个列表，其中包含每个需要发送的电子邮件的一个条目。

Answer 2

你是怀疑的，你必须遍历你得到的数组，但是像这样：

// First create the final array
$emails_to_send = array();
foreach($unread as $object) {
    // Add new array element with the email key
    $emails_to_send[$object->user[0]->email] = array(
        'first_name' => $object->user[0]->first_name,
        'last_name' => $object->user[0]->last_name,
        'project' => $object->project
    );
}

var_export($emails_to_send);

结果你会看到类似的东西：

array(
    'user@emailaddress.com' => array(
        'first_name' => 'User',
        'last_name'  => 'Lastname',
        'project' => array(
            "id" => 422,
            "name" => "Project Number 1",
            "slug" => "Tdc3de97",
            "uri_hash" => "project-number-1",
            ...
        )
    ),
    ...
)

通过循环对象来构建数组
