Php 如何通过$u_activity[$key]和$u_activity_event[$key]结果集合并结果集返回

我有一个表

mst\u event

，可以从中提取

'id','title', 'created_at', 'updated_at', 'imported', 
'import_url', 'cover_type', 'profile_image' 

在

$u\u活动中

和

start_date', 'location' 

在

$u活动\u事件中

在这里，我希望将

$u activity

和

$u activity\u event

返回的结果集组合在一起，也就是说，在这里，我希望得到以下形式的结果：-

        "type": "event",
        "id": "999999",
        "title": "EVENT TITLE",
        "created_at": "22 Oct 2019",
        "updated_at": "22 Oct 2019",
        "imported": "0",
        "import_url": null,
        "cover_type": 0,
        "profile_image": "",
        "description": "",
        "post_url": "http://localhost:8100/view-event/999999"
        "start_date": "12 Nov 2019",
        "location" : "Bangalore"

这是我的密码：-

不管使用哪种语言，总体思路都是构建结果集对象

function make_u_result_set($u_activity, $u_activity_event){
    $result = array();
    foreach ($u_activity as $key => $value){ 
        array_push($result, $key => $value);
    } 

    foreach ($u_activity_event as $key => $value){ 
        array_push($result, $key => $value);
    } 

    return $result

}

更好

function add_data_to_array($array_to_add_data_to, $array_to_get_data_from){
    foreach ($array_to_get_data_from as $key => $value){ 
        array_push($array_to_add_data_to, $key => $value);
    } 
    return $array_to_add_data_to
}

$result = array_merge($u_activity,$u_activity_event);

那你就可以了

$result = array();
add_data_to_array($result, $u_activity);
add_data_to_array($result, $u_activity_event);
//echo json_encode($result);

更好

function add_data_to_array($array_to_add_data_to, $array_to_get_data_from){
    foreach ($array_to_get_data_from as $key => $value){ 
        array_push($array_to_add_data_to, $key => $value);
    } 
    return $array_to_add_data_to
}

$result = array_merge($u_activity,$u_activity_event);
