Php 具有嵌套对象的json web服务

您好，我正在为一名医生制作一个应用程序，我有两个表一个病人表和一个咨询表，与一对多关系相关。当我创建一个web服务时，我创建了两个web服务，一个用于病人，一个用于咨询，但我在ios应用程序中遇到了一些复杂问题 我需要的是只创建一个带有嵌套对象的web服务，这意味着每个患者都将在web服务内的一个数组中进行咨询== 有人能帮我吗

以下是患者web服务：

<?php 
header('Content-Type: application/json; charset=utf-8');
include('settings.php');
mysql_connect($host,$user,$password);
mysql_select_db($base);

mysql_query('SET CHARACTER SET utf8');

$req = "select * from patient";
$sql=mysql_query($req);
$nn=mysql_num_rows($sql);

$items = array("items" => NULL);

while ($data=mysql_fetch_array($sql))
{
    $items["items"][] = array(
        "id_patient" => $data['id_patient'],
        "nom" => $data['nom'],
        "prenom" => $data['prenom'],
        "Sexe" => $data['Sexe'],
        "date_de_naissance" => $data['date_de_naissance'],
        "lieu_de_naissance" => $data['lieu_de_naissance'],
        "adresse" =>$data['adresse'],
        "latitude" => $data['latitude'],
        "longitude" => $data['longitude'],
        "telephone" => $data['telephone'],
        "email" => $data['email'],
        "situation_familiale" => $data['situation_familiale'],
        "profession" => $data['profession'],
        "numero_securite_sociale" => $data['numero_securite_sociale'],
        "taille" => $data['taille'],
        "poids" => $data['poids'],
        "situation_familiale" => $data['situation_familiale'],
        "groupe_sanguin" => $data['groupe_sanguin'],
        "allergies" =>$data['allergies'],
        "antecedents_chirurgicaux" => $data['antecedents_chirurgicaux'],
        "antecedents_medicaux" => $data['antecedents_medicaux'],
        "antecedents_familiaux" => $data['antecedents_familiaux'],
                );
}   
    echo json_encode($items,JSON_UNESCAPED_UNICODE);
?>

这里是咨询网络服务

<?php

include('settings.php');
mysql_connect($host,$user,$password);
mysql_select_db($base);
mysql_query('SET CHARACTER SET utf8');



$patient = (int) $_GET['patient'];
//where id_patient= '".$patient."' 
$req = "select * from consultation ";
$sql=mysql_query($req);
$nn=mysql_num_rows($sql);

$items = array("items" => array());

while ($data=mysql_fetch_array($sql))
{
    $item = array(
                  "id_consultation" => $data['id_consultation'],
                  "id_patient" => $data['id_patient'],

                  );

    array_push($items['items'], $item);

        }
