在Tripadvisor JSON API文件中获取三个对象的PHP值

Question

Been struggling with this for too long now, so am kindly asking for your help.

How can I, using PHP, get the values of the text fields in the reviews of which there are three in this JSON file below.

Want to use a foreach loop for this, thanks for helping me out!

Answer 1

It doesn't seem like you need a foreach to fetch the reviews element. Not sure if I understood your question correct, but did you want something like this:

$assoc_json = json_decode($your_json, true);
var_dump($assoc_json['reviews']);

The above turns your json into an associative array, and just access the review element.
