JSON PHP Querying

Question

I have a question about querying JSON structures that make use of nested objects. In order to explain, I will use some examples.

For Examples Sake, the variable $json is a JSON file:

movies [{"name":"good movie", "poster":"link"}]

Normally after I've used the json_decode() function on a JSON file I can do something like

$newFiles = $json["movies"];

foreach ($newFiles as $file) {
$name = $file["name"]; }

But, lets say I have this JSON File:

movies[{"name":"good movie", "poster": {"original":"link", "smaller":"link"}}]

How would I get the value of "original", I've tried doing something like:

$newFiles = $json["movies"];

foreach ($newFiles as $file) {
$poster = $file["poster" -> "original"]; }

That, however, doesn't work. I can't find the appropriate syntax to query this. Any help appreciated, thanks in advance!

Is the answer provided is answering the question?

When you decode your json with json_decode(), set the second parameter to true, as so:

<?php
$movies = '[{"name":"good movie", "poster": {"original":"link", "smaller":"link"}}]';
$movieArray = json_decode($movies,true);

foreach($movieArray as $movie){
    print_r($movie['poster']['original']);
}
?>

This will allow you to convert returned objects into associative arrays. Therefore it is possible to do something like $movie['poster']['original'].
