цикл через объект json в php

Question

У меня есть объект json, и я хочу добавить в него поле «количество». Мой код here

while($row=mysql_fetch_array($result)){ 
    $posts = json_decode($row['value'],true); 
    array_push($response,$posts); 
    } 
    //print_r($response); 
    foreach($response as $value){ 
     //$plus +=1; 
     $plus = $plus+$value['quantity']; 
    } 

print_r($response) затем дает:

Array

    [0] => Array 
     (
      [0] => Array 
       (
        [srno] => 1

Answer 1

попробовать этот

plus = 0; 
foreach($response as $value){ 
    //$plus +=1; 
    foreach($value as $val) 
    { 
    $plus = $plus+$val['quantity']; 
    } 
} 

Answer 2

Я думаю, что проблема заключается в ваш массив является двойным вложенным. У вас есть 2D массив пар ключ => значение

foreach($response as $array){ 

    foreach($array as $value){ 
     $plus = $plus+$value['quantity']; 
    } 

}
