如何在 PHP 中使用 cURL 检索和解析 jSON 数据
使用 cURL 和 PHP,您可以从 URL 检索 JSON 数据并对其进行解码以便在您的 PHP 应用程序中使用。操作方法如下:
检索 jSON 数据
// Initiate cURL $ch = curl_init(); // Set cURL options curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the response instead of printing it curl_setopt($ch, CURLOPT_URL, $url); // Set the URL to retrieve the jSON from // Execute the request and get the response $result = curl_exec($ch); // Close the cURL session curl_close($ch); // Parse the jSON response $data = json_decode($result, true); // Decode the response as an associative array
从 jSON 对象中提取数据
检索后JSON 数据,您可以将需要的值提取到 PHP 变量中。操作方法如下:
$title = $data['threads']['38752']['title']; $userId = $data['threads']['38752']['user_id']; $username = $data['threads']['38752']['username']; $postDate = $data['threads']['38752']['post_date']; $sticky = $data['threads']['38752']['sticky']; $discussionState = $data['threads']['38752']['discussion_state']; $discussionOpen = $data['threads']['38752']['discussion_open']; $message = $data['threads']['38752']['content']['content']['226167']['message'];
解决数组访问问题
要访问包含嵌套数组的数组中的元素,请使用以下语法:
// Access the "count" element of the outer array $count = $array['count']; // Access the "thread_id" element of the first inner array (thread with id 13) $threadId = $array['threads'][13]['thread_id'];
请注意,对于名为“[count]”的元素,您可以直接访问它,而无需将其括在括号中PHP,即 $count = $array["count"];.
