我有一個調查表，答案和用戶表。答案和調查表由user_id也用戶連接，調查與user_id連接。如何在php中顯示另一個數組中的一個數組？
我想爲調查顯示答案和用戶以及評論。評論在調查表內。
我想要得到的結果，在這個格式：
{
result:1,
message:'success',
survey:[
{
answers:
[
],
user:
{
}
comment:
},
{
answers:
[
],
user:
{
}
comment:
}
]
}
getAllSurveyByDoctor功能：
function getAllSurveyByDoctor($user_id)
{
$database = new SurveyDatabase(SurveyConstants::DBHOST,SurveyConstants::DBUSER,SurveyConstants::DBPASS,SurveyConstants::DBNAME);
$dbConnection = $database->getDB();
$stmt = $dbConnection->prepare("SELECT * from survey where `user_id` = ?");
$stmt->execute(array($user_id));
$survey = $stmt->fetchAll(PDO::FETCH_ASSOC);
$surveys = array();
$answers = array();
if (count($survey) > 0) {
foreach($survey as $row)
{
$stmt = $dbConnection->prepare("SELECT answer.answer_id, answer.survey_id, answer.question_id, answer.rating, answer.user_id, question.question_id, question.question, question.type FROM `answer` INNER JOIN `question` ON
answer.question_id = question.question_id WHERE answer.user_id = ? and answer.survey_id = ?");
$s_id = $row['survey_id'];
$stmt->execute(array($user_id,$s_id));
$answer = $stmt->fetchAll(PDO::FETCH_ASSOC);
$stmt = $dbConnection->prepare("SELECT users.user_id,users.email_id,users.pass,users.address,users.name,survey.survey_id,survey.user_id FROM `users` INNER JOIN `survey` ON users.user_id = survey.user_id WHERE users.user_id = ?");
$stmt->execute(array($user_id));
$user = $stmt->fetch(PDO::FETCH_ASSOC);
$comment = $row['comment'];
// $surveys[] = $row;
$answers = $answer;
$surveys[] = $answers;
$surveys[] = $user;
$surveys[] = $comment;
}
$response = array("status" => 1, "message" => "Success", "surveys" => $surveys);
return json_encode($response);
}
else {
$response = array("status"=>-1,"message"=>"surveys list is empty");
return json_encode($response);
}
}
我得到的結果是這樣的：

我得到一些什麼格式與我想要的相同。之後，我得到了答案數組，用戶和評論。但我怎麼能命名呢？無法從此結果中識別出答案，用戶和評論。我想命名它。我怎麼能夠？謝謝。
$ surveys [] =正在爲數組順序添加一個新值。如果你想命名它。使用鑰匙計數器。像$ survey [$ i] ['user_id'] = $ user，$ surveys [$ i] ['comment'] = $ comment。確保增加計數器。 –
亞歷克西斯的解決方案也適用。一種不需要櫃檯的方法。 –
