在PHP中循环遍历json响应

时间：2015-10-31 10:06:11

标签： php arrays json api response

我正在使用y和json_decode来解析PHP中的json响应，但是当我尝试访问它的元素时，它不起作用，这是响应的样子

TRUE

$ responseData = json_decode（$ response，TRUE）; //应该将其转换为数组

我正在访问BCLS.secondaryCallResponse({"items":[{"id":4377466391001,"name":"Sample Video 2","creationDate":"1438012370879","renditions":[{"audioOnly":false,"controllerType":"DEFAULT","displayName":"Sample

        $sample=json_decode($data);
        var_dump($sample->items);

答案 1 :(得分：1)

您有两种选择：

1）转换为关联数组 - foreach ($json['items'] as $item) { //for example, show first rendition for each item print_r($item['renditions'][0]); } ：

$json = json_decode('{"items":[ ...')

2）转换为stdClasses - foreach ($json->items as $item) { //for example, show first rendition for each item print_r($item->renditions[0]); } ：
