将多个json对象合并为单个对象

Question

我有这样的数据json：

[
{
    "created_at": "2019-02-17 15:08:11",
    "description": "black,white",
    "id": 1,
    "name": "mamat",
    "updated_at": "20169-02-17 15:08:11"
},
{
    "created_at": "2019-02-17 15:08:31",
    "description": "yellow,red,green",
    "id": 2,
    "name": "klomangan",
    "updated_at": "2019-02-17 15:08:31"
}

]

但是，我想要这样的json，合并名称和描述。

{
"name": "mamat klomangan",
"description": "black,white,yellow,red,green"   
}

注意：我正在使用Laravel / PHP和SQL

假设您要使用相同的键合并两个json对象，请遵循以下功能：

$people = '[{"name":"John", "color":"green"}, 
           {"name":"Mary", "color":"green"}, 
           {"name":"Bob", "color":"red"}]';

$people_json = json_decode($people, True);

$merged_array = array();
foreach ($people_json as $person) {
    if (isset($people_by_color[$person['color']])) {
        $people_by_color[$person['color']]['name'] .= ', ' . $person['name'];
        $people_by_color[$person['color']]['color'] .= ', ' . $person['color'];
    } else {
        $people_by_color[$person['color']] = $person;
    }
}

$merged_array_final = array_values($people_by_color); // Turn into indexed array

print_r($merged_array_final);
