Недопустимое смещение строки в многомерном массиве

Question

Я пытаюсь получить файл JSON с отдельного веб-сайта, прочитать этот файл и затем декодировать его в многомерный массив. Пока что на данный момент это работает. Тем не менее, когда я пытаюсь разбить все это на переменные для эха, он идет не так, когда его 4 уровня глубоко. Вы можете увидеть фактический файл JSON по ссылке в коде PHP, а ниже приведен код PHP, который я использую. Конкретными переменными, которые имеют проблемы, являются цены в 2 областях и правила. Буду признателен за любую помощь, которую кто-то может оказать с этим.

Answer 1

Вы должны упомянуть имя массива для извлечения содержимого из массива, вот пример кода и исполнитель с маленькой буквой "a", а не с большой буквы

Редактировать согласно запросу на комментарий

Получите массив 'legalities', в котором строка, разделенная с помощью implode и затем взорвающаяся с, и конвертируйте в массив для печати этих

Примечание: будут только значенияимпортировано с помощью implode, а не ключей

<?php
// error_reporting(0);
// header('Content-type: application/json');
$path           = 'https://www.mtgjson.com/json/LEA.json';
$FileContents   = file_get_contents($path);
$cards          = json_decode($FileContents, true);

foreach($cards['cards'] as $mtgcard) {

    echo '<br>' .$course_data1 = $mtgcard['artist']; 

    $cards_legalities = implode($mtgcard['legalities'],",");
    $myArray = explode(',', $cards_legalities);
    echo $myArray[0];// 1st array

    //Multidimensional Array for your updated question
    $cards_prices_paper = implode($mtgcard['prices']['paper'],",");
    $prices_paper_array = explode(',', $cards_prices_paper);
    echo $prices_paper_array[0];

    $rulings_date =  implode(', ', array_column($mtgcard['rulings'], 'date'));
    $rulings_date_array =  explode(",", $rulings_date);
    echo $rulings_date_array[0];
}
?>
