我的
PHP代码：
$obj = json_decode($data);
print $obj->{'name'};
虽然它适用于非数组,但我无法为我的生活找出如何打印“评论”数组中的所有值.
我想要做的是循环执行这个响应,可能是使用forreach(),导致一个列表,其中包含响应中每个评论的评级和摘录.
任何指导/方向非常感谢..
下面是我正在使用的JSON. (这是Yelp API的回应).

您可能会遇到麻烦,因为评论是一个数组,您正在尝试以JSON对象身份访问它.
$obj = json_decode($data,TRUE);
for($i=0; $i<count($obj['reviews']); $i++) {
echo "rating is " . $obj['reviews'][$i]["rating"] . " and the excerpt is " . $obj['reviews'][$i]["excerpt"] . "<BR>";
}
