访问数组 In Json 响应 In PHP 来自 REST API 来自 Invision 社区的响应

Question

我正在尝试从 Invision 社区 REST API 调用的 Json 响应内部访问“结果”数组。我不确定如何从 PHP 代码中过滤到结果数组，如下所示。一旦我过滤到它，我想将它回显到屏幕上，就像当前显示完整响应的方式一样。任何帮助将不胜感激！

PHP代码

<?php
    $communityUrl = 'https://website.net/invisioncommunity';
    $apiKey = 'apikey';
    $endpoint = '/core/members';

    $curl = curl_init( $communityUrl . 'api' . $endpoint );
    curl_setopt_array( $curl, array(
        CURLOPT_RETURNTRANSFER  => TRUE,
        CURLOPT_HTTPAUTH    => CURLAUTH_BASIC,
        CURLOPT_USERPWD     => "{$apiKey}:"
    ) );
    $response = curl_exec( $curl );
    $resArr = array();
    $resArr = json_decode($response);
    
    $resultsArr = cleanResponse($response);
    
    echo "<pre>"; print_r($resultsArr); echo "</pre>";    
    function cleanResponse($arr)
    {
        $element = $arr['results'];
        return $element;
    }

对您的代码进行一些小改动应该可以解决您的问题：

要返回关联数组，请使用 true 作为 json_decode()

$resArr = json_decode($response, true);

使用关联数组 $resArr 作为函数的参数 cleanResponse:

$resultsArr = cleanResponse($resArr);

现在 $resultsArr 包含 results 子数组，您可以使用例如输出print_r()
