我有来自Google API的以下JSON，我想提取cse_image -> src并在PHP数组中将其用作arr[0]作为第一个，arr[1]作为第二个，依此类推。

我想使用PHP提取JSON，然后使用
访问它 arr[0]：http://img3.wikia.nocookie.net/__cb20130410025818/gravityfalls/images/thumb/5/54/Welovefine_rainbow_gnome.jpg/500px-Welovefine_rainbow_gnome.jpg

如何使用json_decode或任何其他类似方法执行此操作
答案 0 :(得分：1)
$data = json_decode($string, true);
echo $data['items'][0]['pagemap']['cse_image'][0]['src'];
echo $data['items'][1]['pagemap']['cse_image'][0]['src'];
