Stackoverflow API在数组PHP中获得答案

Question

我正在尝试使用stackoverflow API，我希望在php数组中获得问题的答案。到目前为止，这是我的PHP代码：

<?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);


?>

我想将一个问题的答案存储在一个名为答案的数组中，以便我可以使用for循环访问它们。

我得到的答案是：

stdClass Object

    [total] => 2618591
    [page] => 1
    [pagesize] => 30

Answer 1

不确定要提取哪个属性，但我认为它是'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']);
}

应该这样做。
