如何在 php 中将数据从一个数组存储到另一个数组

Question

我需要什么

我需要获取一些键值并存储在另一个数组中。

api数据

php代码

          $noty = array();
          $notification=json_decode($notifications,true);
            //print_r($notifications);
             foreach($notification as $key =>$value)
             {

                $id['id']=$value['id'];
                $name['name']=$value['name'];
                 $abbr_name['abbr_name']=$value['abbr_name'];
                 $startDate['startDate']=$value['startDate'];
                 $endDate['endDate']=$value['endDate'];
                  $city['city']=$value['city'];
                   $country['country']=$value['country'];
                    $data[$key]=array_push($noty,$id,$name,$abbr_name, $startDate,$endDate,$city,$country);

             }

       $n=json_encode($noty,true);

我需要将一些数据分组到数组中。

输出应该是这样的：

                    Array
            (
            [0] => Array
            (
            [id] => 180462

            [venue_name] => Delhi Haat
            [startDate] => 2015-06-05
            [endDate] => 2015-06-07
            [city] => New Delhi
            [country] => India
            [country_url] => india
            [country_shortname] => India


            )

            [1] => Array
            (
            [id] => 185988

            [membership] => 
            [name] => International Conference On Advances in Electrical, Power Control, Electronics and Communication Engineering
            [abbr_name] => AEPCECE
            [paid] => 
            [event_wrapper] => 
            [event_samll_wrapper] => http://im.gifbt.com/industry/55-350x210.jpg
            [event_url] => aepcece

            [venue_name] => Jawaharlal Nehru University
            [startDate] => 2015-06-06
            [endDate] => 2015-06-07
            [city] => New Delhi
            [country] => India

            )

            [2] => Array
            (
            [id] => 193245

            [name] => International Conference on Advances in Healthcare Management Services
            [abbr_name] => International Conference on Advances in Healthcare

            [event_samll_wrapper] => http://im.gifbt.com/industry/55-350x210.jpg
            [event_url] => international-conference-on-advances-in-healthcare
            [website] => http://www.iimahd.ernet.in/cmhsconf2015/
            [eventType] => 2
            [venue_name] => Indian Institute of Management
            [startDate] => 2015-06-06
            [endDate] => 2015-06-07
            [city] => Ahmedabad
            [country] => India

            )

            )

它的 o/p 数组有问题

 Array
(
[0] => Array
    (
        [id] => 180462
    )

[1] => Array
    (
        [name] => India International Bearing Expo New Delhi
    )

[2] => Array
    (
        [abbr_name] => India International Bearing Expo
    )

[3] => Array
    (
        [startDate] => 2015-06-05
    )

[4] => Array
    (
        [endDate] => 2015-06-07
    )

[5] => Array
    (
        [city] => New Delhi
    )

请指出我哪里做错了。
我需要一些键和值并存储在另一个数组中。 .

你的错误是你使用 array_push 的方式不对：你给 array_push 的每个参数都会在数组中添加另一行。您要做的是一次只添加一行，其中包含所需的数据。

你应该这样做:

<?php

$noty = array();
$notification=json_decode($notifications,true);
//print_r($notifications);
foreach($notification as $key =>$value)
{
    array_push($noty, array(
        'id' => $value['id'],
        'name' => $value['name'],
        'abbr_name' => $value['abbr_name'],
        'startDate' => $value['startDate'],
        'endDate' => $value['endDate'],
        'city' => $value['city'],
        'id' => $value['id'],
        'country' => $value['country'],
        ));
}
$n=json_encode($noty,true);
