【问题描述】：

我只想获取特定关联数组元素的数据。我怎样才能做到这一点？

代码如下：

<?php    

$ch = curl_init();
$id=647672630230;
curl_setopt($ch, CURLOPT_URL, "affiliate-feeds.snapdeal.com/feed/product?id=$id");
curl_setopt(
    $ch, CURLOPT_HTTPHEADER,
    array(
        'Snapdeal-Affiliate-Id:133419',
        'Snapdeal-Token-Id:cf72ba3b7c2f47e3e0b09cd7e8613c',
        'Accept:application/json'
    )
);

$response = curl_exec($ch);
curl_close($ch);

// work with $response here:
$result = json_decode($response, TRUE);


?>

它在$result中返回这个结果：

{"id":647672630230,"title":"Spacewood Carnival Queen Bed","description":"Non-cancellable: Order can't be cancelled after 48 hours Color : Wenge Ideal Mattress Size (L X B in cm) : Standard mattress size for bed: 150 x 195 cm (Mattress is not included in the sales package) Finish : Melamine Size : Queen Material: Particle Board Overall Height (cm)-80 cm, Overall Width (cm)-163 cm, Overall Depth (cm)-206 cm Queen Size Bed with No Storage Warranty: 12 Months Weight Bearing Capacity: 250 Kgs.

但我只想要标题和描述细节。我怎样才能得到这些？

你可以像这样访问你的数组：

$result['title']

$result['description']

你可以通过我的测试看到这个工作： http://sandbox.onlinephpfunctions.com/code/be2f8f5152e217247a7f82f3a08f699976763995
