json output преобразовать в строку php

Question

Ниже мой рабочий api, но результат для "echo $data" только "array" и для "echo $data["data"]["operatorid"]" ничего не гаснет. Так как преобразовать json reponse в php строку, а также получить конкретные значения из того же

$opts = array(
'http'=>array(
'method'=>"GET", 
'header'=>"X-Mashape-Key: XXXXXXXX"    
) 
); 

$context = stream_context_create($opts); 
$res = file_get_contents('https://tariff-plan-api-datayuge.p.mashape.com/index.php?circleid=kerala&limit=50&operatorid=BSNL&recharge_type=top', false, $context); 
$data = (json_decode($res, true)); 
echo $data["data"]["operatorid"]; 

ответ JSon:

Answer 1

$data имеет многомерный массив - «данные», который сам держит несколько массивов.

echo $data["data"]["operatorid"] ничего не вернет, потому что вы не указали, какой из этих массивов вы хотите распечатать operatorid.

либо указать, какой массив вы ориентируетесь со следующими

$data["data"][*index*]["operatorid"]

или цикл через массив данных $ как так

foreach($data as $Adata){ 
    foreach($Adata as $arr){ 
     echo $arr['operatorid']; 
    } 
}

Это JSON строка превращается в объект PHP, который имеет имущество, которое называется data, которое представляет собой набор объектов

Выходной сигнал от print_r()

stdClass Object 
(
    [data] => Array 
     (
      [0] => stdClass Object

     ) 

) 

Так ссылаться на отдельный элемент вам нужно будет использовать этот синтаксис

$context = stream_context_create($opts); 
$res = file_get_contents('https://tariff-plan-api-datayuge.p.mashape.com/index.php?circleid=kerala&limit=50&operatorid=BSNL&recharge_type=top', false, $context); 

$data = (json_decode($res)); 
echo $data->data[0]->operatorid; 

Это может быть проще понять, если вы используете имя переменной, кроме $data так

$jsonObj = (json_decode($res)); 
echo $jsonObj -> data[0] -> operatorid; 

Или если вы обрабатываете все события

$jsonObj = (json_decode($res)); 
foreach ($jsonObj -> data as $data) { 
    echo $data -> operatorid; 
}
