PHP客户端验证https证书

问题描述：

我需要创建一个充当客户端的php并使用https下的一些Web服务。
我的问题是我还要验证服务器证书。我需要知道我有正确的服务器，并且没有一个中间充当服务器。
有人可以帮帮我吗？

I need to create a php that will act as a client and use some web services under https. My Problem is that I also want to verify the server certificate.I need to know that I have the right server and that there is no one the middle that acts as the server. Can someone help me please?

谢谢！

如果您有卷曲扩展名，可以将其配置为在连接时验证证书。

If you have the curl extension, it can be configured to verify a certificate on connection.

http://php.net/manual/en/function.curl-setopt.php

// As of writing this, Twitter uses Verisign, Google uses Eqifax
$exampleUrl = 'https://twitter.com/'; // Success
$exampleUrl = 'https://google.com/';  // Fails

// create a new CURL resource
$ch = curl_init($exampleUrl);

// enable verification
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);

// list of CAs to trust
// If the remote site has a specific CA, they usually have a .crt
// file on their site you can download.  Or you can export key items from
// some browsers.
// In this example, using: Verisign [1]
curl_setopt($ch, CURLOPT_CAINFO, __DIR__ . '/ca_bundle.crt');
// - or -
curl_setopt($ch, CURLOPT_CAPATH, __DIR__ . '/ca_certs/');

// If the remote site uses basic auth:
curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . $password);

// And a helpful option to enable while debugging
//curl_setopt($ch, CURLOPT_VERBOSE, true);

// defaults to stdout, don't want that for this case.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$page = curl_exec($ch);
