Stackoverflow API получает ответы в массиве PHP

Question

Я пытаюсь использовать API-интерфейс stackoverflow и хочу получить ответы на вопрос в массиве php.Итак, вот мой php-код:

<?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);


?>

Я хочу сохранить ответы на вопрос в массиве, называемом ответы, чтобы я мог получить к ним доступ с помощью цикла for.

Ответя получаю это:

Answer 1

Не знаю точно, какое именно свойство вы хотите извлечь, но я предполагаю, что это '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']);
}

Это нужно сделать.
