我可以打电话curl_setopt与CURLOPT_HTTPHEADER多次设置多个标头？
$url = 'http://www.example.com/';
$curlHandle = curl_init($url);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array('Content-type: application/xml'));
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, array('Authorization: gfhjui'));
$execResult = curl_exec($curlHandle);

Following what curl does internally for the request (via the method outlined in this answer to "Php - Debugging Curl") answers the question: No, it is not possible to use the curl_setoptcall with CURLOPT_HTTPHEADER. The second call will overwrite the headers of the first call.
遵循 curl 在内部为请求所做的事情（通过此对“Php - Debugging Curl”的回答中概述的方法）回答了这个问题：不，不能将curl_setopt调用与CURLOPT_HTTPHEADER. 第二个调用将覆盖第一个调用的标头。
Instead the function needs to be called once with all headers:
相反，该函数需要使用所有标头调用一次：
$headers = array(
'Content-type: application/xml',
'Authorization: gfhjui',
);
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);

相关（但不同）的问题是：
- How to send a header using a HTTP request through a curl call?(curl on the commandline)
- How to get an option previously set with curl_setopt()?(curl PHP extension)
- 如何通过 curl 调用使用 HTTP 请求发送标头？（在命令行上卷曲）
- 如何获得先前使用 curl_setopt() 设置的选项？（卷曲 PHP 扩展）

Other type of format :
其他类型的格式：
$headers[] = 'Accept: application/json';
$headers[] = 'Content-Type: application/json';
$headers[] = 'Content-length: 0';
curl_setopt($curlHandle, CURLOPT_HTTPHEADER, $headers);
