PHP获取两个带有不同“Set- cURL”的响应头

// 创建一个cURL句柄
$ch = curl_init();

// 设置请求的URL
curl_setopt($ch, CURLOPT_URL, "http://example.com");

// 执行请求并获取响应头
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);

// 关闭cURL句柄
curl_close($ch);

// 解析响应头
$headers = [];
$headerLines = explode("\r\n", $response);
foreach ($headerLines as $headerLine) {
    if (strpos($headerLine, "Set-CURL") !== false) {
        $headers[] = $headerLine;
    }
}

// 打印获取到的响应头
foreach ($headers as $header) {
    echo $header . "\n";
}
