PHP 添加到在 foreach 中创建的现有数组

Question

我从数据库中选择值并在 foreach 循环中将这些值添加到数组中，这有效。

在此之后我在第二个查询中选择其他值，我想将这些值添加到同一个数组中，我该如何实现？

请注意，我还不关心代码的安全性。

我的（简化）代码如下；

$users_arr = array();
// first query
$db->setQuery("SELECT id, name, username, email FROM sometable WHERE name = '$name' ");
$results = $db->loadObjectList();

foreach ($results as $result) {
    $userid = $result->id;
    $name = $result->name;
    $username = $result->username;
    $email= $result->email;
    $users_arr[] = array(
      "id" => $userid, 
      "name" => $name, 
      "username" => $username, 
      "email" => $email);
}

// second query
$db->setQuery("SELECT status AS wb_status FROM anothertable ");
$wb = $db->loadObject();

$wb_status = $wb->wb_status;

// add to original array 
$users_arr[] = array("wb_status" => $wb_status);

echo json_encode($users_arr);
exit();

这会产生；

[
  {
    "id": "981",
    "name": "jo",
    "username": "jo123",
    "email": "jo@example.com"
  },
  {
    "wb_status": "Complete"
  }
]

我需要这种格式；

[
  {
    "id": "981",
    "name": "jo",
    "username": "jo123",
    "email": "jo@example.com",
    "wb_status": "Complete"
  }
]

运行第二次查询 before 首先将元素添加到数组 foreach:

// second query becomes first
$db->setQuery("SELECT status AS wb_status FROM anothertable ");
$wb = $db->loadObject();

$wb_status = $wb->wb_status;

$users_arr = array();
// first query becomes second
$db->setQuery("SELECT id, name, username, email FROM sometable WHERE name = '$name' ");
$results = $db->loadObjectList();    

foreach ($results as $result) {
    $userid = $result->id;
    $name = $result->name;
    $username = $result->username;
    $email= $result->email;
    $users_arr[] = array(
      "id" => $userid, 
      "name" => $name, 
      "username" => $username, 
      "email" => $email
      "wb_status" => $wb_status, // Here
    );
}

echo json_encode($users_arr);
exit();

更新：另一种方法是遍历[=13=]并向每个元素插入所需的数据：

// ...
$db->setQuery("SELECT status AS wb_status FROM anothertable ");
$wb = $db->loadObject();

$wb_status = $wb->wb_status;

// I use `&` here so as to pass `$item` as a
// reference to original item in `$users_arr`
foreach ($users_arr as &$item) {
    $item["wb_status"] = $wb_status;
}

echo json_encode($users_arr);
exit();
