证书CA软件包文件：PEM - PHP / cURL - 本地安装...？

我使用Windows Server 2008 R2（使用IIS），PHP 5.6.0和cURL 7.36.0来测试PayPal的TLS测试网址：

I'm using Windows Server 2008 R2 (with IIS), PHP 5.6.0 and cURL 7.36.0 to test against PayPal's TLS test URL:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://tlstest.paypal.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSLVERSION, 6); // CURL_SSLVERSION_TLSv1_2
curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '\cacert.pem');
$result = curl_exec($ch);
curl_close($ch);

当我使用 CURLOPT_CAINFO 和 cacert.pem 来自 http://curl.haxx.se /docs/caextract.html 它的工作原理，我得到：

When I use CURLOPT_CAINFO and cacert.pem from http://curl.haxx.se/docs/caextract.html it works and I get:

PayPal_Connection_OK

PayPal_Connection_OK

当我不使用 CURLOPT_CAINFO 时出现这个错误：

When I don't use CURLOPT_CAINFO I get this error:

SSL证书问题：无法获取本地颁发者证书

SSL certificate problem: unable to get local issuer certificate

p>

I've tried this:

1. mmc


2. 文件>添加/删除管理单元


3. Certificates（Local Computer）


4. 受信任的根证书颁发机构>证书


5. 所有任务>导入


6. cacert.pem


7. 消息：导入成功

1. mmc
2. File > Add/remove snap-in
3. Certificates (Local Computer)
4. Trusted Root Certification Authorities > Certificates
5. All tasks > Import
6. Select cacert.pem
7. Message: "The import was successful"

但是这没有什么区别，我仍然必须使用 CURLOPT_CAINFO 才能工作。

However this has made no difference, I still have to use CURLOPT_CAINFO for it to work.

有没有办法我可以安装所有这些根证书在我们的Windows服务器，所以我不必使用 CURLOPT_CAINFO 和 cacert

Is there any way I can install all these root certificates on our Windows Server so that I don't have to use CURLOPT_CAINFO and cacert.pem with every call I make..?
