Рациональный парсинг JSON в PHP

Рейтинг: -4Ответов: 1Опубликовано: 21.05.2023

Я хочу найти наиболее рациональный способ парсинга JSON в PHP.

К примеру, у меня есть данный array:

{
"response": {
    "count": 254,
    "items": [
        {
            "album_id": 136592355,
            "date": 1525617677,
            "id": 456317315,
            "owner_id": 1,
            "sizes": [
                {
                    "height": 130,
                    "type": "m",
                    "width": 93,
                    "url": "https://sun9-79.userapi.com/impf/rD7Ugfhcf7bKIJ4-d8l8I-RkaTwVN-IRoxt9sg/heuH_mKDOcY.jpg?size=93x130&quality=96&sign=25840dcf9a57237ca0083d2f37151218&c_uniq_tag=U_3djTlFZEsWZj0mNQb_mUcxKGDGleSDROhOQVq4YCA&type=album"

            "text": "",
            "has_tags": false
        }
    ]
}

}

Мне нужен код, который будет выводить все url с "type" : "m", но так чтобы этот код не выглядел как:

foreach(){
   foreach(){
      foreach(){
         foreach(){
            foreach(){
            }
         }
      }
   }
}

А чтобы это была универсальная функция, которая искала бы в array указанный объект без кучи циклов и огромного количества постоянно повторяющегося кода для каждого запроса...

$array = [];

foreach ($data['response']['items'] as $item) {
    foreach ($item['sizes'] as $size) {
        if ($size['type'] !== 'm') {
            continue;
        }
        
        $array[] = $size['url'];
    }
}

var_dump($array);

или даже с одним foreach

$array = [];

foreach ($data['response']['items'] as $item) {
    $filteredSizes = array_filter(
        $item['sizes'], 
        fn($size) => $size['type'] === 'm'
    );

    $array = [
        ...$array,
        ...array_map(fn($size) => $size['url'], $filteredSizes)
    ];
}

var_dump($array);
