Stackoverflow API getting answers in array PHP - php

Question

I'm trying to use the stackoverflow API and I want to get answers of a question in a php array. So far here is my php code:
<?php
//KEY
$string = "key=my_key";
//Call stack API .$string
$stack_url = "compress.zlib://http://api.stackoverflow.com/1.1/questions";
//Get and Store API results into a variable
$result = file_get_contents($stack_url);
$jsonArray = json_decode($result);
print_r($jsonArray);
//echo($jsonArray->questions[0]->question_answers_url);
//var_dump($jsonArray);
?>
I want to store the answers of a question in an array called answers so that I can access them with a for loop.
The answer i get is :
stdClass Object

Not sure exactly which property you want to extract, but I assume it's the 'question_answers_url'.
$answersArray = Array();
for($i=0;$i<count($jsonArray['questions']);$i++){
//assuming it is the 'question_answers_url' property that you want
array_push($answersArray,$jsonArray['questions'][$i]['question_answers_url']);
}
Ought to do it.
