cURL — PHP 的网络请求库

cURL（Client URL）是 PHP 发送 HTTP 请求的标准方式。调用外部 API、抓取网页、提交表单都靠它。

GET 请求

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.example.com/data");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

POST 请求

curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, [
  "Content-Type: application/json",
  "Authorization: Bearer YOUR_TOKEN"
]);
