通过JSON字符串PHP解析

Question

IM使用JSON新的和有大规模的斗争试图解析此JSON

{ 
    "730": { 
     "success": true, 
     "data": { 
      "price_overview": { 
       "currency": "USD", 
       "initial": 1499, 
       "final": 1499, 
       "discount_percent": 0 
      } 
     } 
    } 
} 

我曾尝试不同的方法，但仍在努力获得的初始值在price_overview

Answer 1

你需要json_decode，然后，只需使用生成的dictionary即可获取该值。就像这样：

$json = <<< JSON 
    { 
    "730": { 
     "success": true, 
     "data": { 
      "price_overview": { 
       "currency": "USD", 
       "initial": 1499, 
       "final": 1499, 
       "discount_percent": 0 
      } 
     } 
    } 
} 
JSON; 

$json_a = json_decode($json, true); 
echo $json_a['730']['data']['price_overview']['initial'];

Answer 2

试试这个：

<?php 
$data = '{"730":{"success":true,"data":{"price_overview":{"currency":"USD","initial":1499,"final":1499,"discount_percent":0}}}}'; 

$json = json_decode(trim($data), true); 

echo '<pre>'; 
print_r($json[730][data][price_overview]); 
echo '</pre>';
