How to call specific data in json object - php

Question

Ok I am making an api call to google places API and getting back a JSON object. I have been able to do work with this object with Ajax but now I have to integrate my code into a Wordpress instance and I am making the API call inside functions.php because I want to use the get_theme_mod(); method.
Since I am fairly new to php I don't know how to output specific data from this object.
My object is below, I am trying to access the reviews returned by this object (all 5). I know I can do this with Ajax fairly easily but I am really struggling with the syntax in PHP.
This is my PHP API call
function do_api_call(){
$url = $my_url;
$data = file_get_contents($url);
$rev = json_encode($data);
echo $rev;
}

Answer 1

Try this:
$rev = json_decode($data,true);
$reviews = $rev["result"]["reviews"];
foreach($reviews as $review){
$author_name = $review["author_name"];
echo $author_name."<br>";
}
