使用php curl和客户端证书时的分段错误

Question

我正在做一个应该连接到RESTful webservice的php应用程序，它需要一个客户端证书。

但是当我使用php curl和客户端ceritifcate时，我遇到了分段错误。

密钥和证书文件是正确的。我在rhel 6上使用php 5.3.3。

任何帮助人员？

<?php

$url = 'https://10xxxxxxxxxxxxxxxxxx';


$data = array(xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx);                                                                    
$data_string = json_encode($data);    

echo($data_string);  
error_reporting(E_ALL);                                                                             

$ch = curl_init($url); 

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");   
curl_setopt($ch, CURLOPT_HTTPHEADER, array(

$result = curl_exec($ch);

echo(htmlentities($result));
