Question

我正在执行GET请求。我需要“组”具有相同关联数组的多个实例（“时间” =>字符串，“会话” => array（））。我的前端使用此特定的.json结构。

我在while循环中使用了array_push。我还尝试构建一个临时数组，然后推送它，但是我推送的最后一个数组会覆盖最后一个。

<?php
// required headers
header("Access-Control-Allow-Origin: *");
header("Content-Type: application/json; charset=UTF-8");

// include database and object files
include_once '../config/database.php';
include_once '../objetos/token.php';
include_once '../objetos/log.php';
include_once '../objetos/agenda.php';
$idLogAccion = 16;

//Leo los parametros


// instantiate database and product object
$database = new Database();
$db = $database->getConnection();


// initialize object
$miAgenda = new agenda($db);


$respuesta_arr=array();
$respuesta_arr["schedule"]=array();
$respuesta_arr["speakers"]=array();

$groups_arr["groups"]=array();
$respuesta_arr["schedule"]["date"]="2018-05-17";
$respuesta_arr["schedule"]["groups"]=array('time'=>'','sessions'=>array());



$listaEventos = $miAgenda->obtenerEventos();
$numeroEventos = $listaEventos->rowCount();

$listSpeakers = $miAgenda->obtenerOradores();
$numeroSpeakers = $listSpeakers->rowCount();

if($numeroSpeakers>0){

    // retrieve our table contents
    while ($row = $listSpeakers->fetch(PDO::FETCH_ASSOC)){

        // extract row
        extract($row);

        $speakers_item=array(
            "idEvento" => $idEvento,
            "nombre" => $nombre." ".$apellido,
            "fotoPerfil" => $fotoPerfil,

你有一个数组

$respuesta_arr=array();

现在您添加组时间表和发言人：

$respuesta_arr["schedule"]=array();
$respuesta_arr["speakers"]=array();

现在您添加嵌套数据：

$respuesta_arr["schedule"]["date"]="2018-05-17";
$respuesta_arr["schedule"["groups"]=array();

现在添加组数据

$respuesta_arr["schedule"]["groups"][] = array('time'=>'','sessions'=>array())

如果愿意，您可以立即执行以下操作：

 $respuesta_arr = array(
    "schedule" => array(
      "date" => "2018-05-17",
      "groups" => array(
         array('time'=>'','sessions'=>array()),
         array('time'=>'','sessions'=>array())
       )
     ),
    "speakers" => array()
 );

您有两个错误：$groups_arr，并且必须使用array(array(...))或[]嵌套数组。您还可以查看以下文档：https://www.php.net/manual/en/language.types.array.php
