I had a errors with Curl and SSL certificate - php

Question

I had a problem. When you send a POST request with the CURL library to HTTPS get the error: SSL certificate problem, verify that the CA cert is OK. Details: error: 14090086: SSL routines: SSL3_GET_SERVER_CERTIFICATE: certificate verify failed. using current certificate.
I tried various certificates FROM http://www.startssl.com/certs/ and FROM http://curl.haxx.se/docs/caextract.html
Tell me what could be the cause of the error?
Here's the code POST request:
curl_setopt($process, CURLOPT_USERAGENT, $this->user_agent);
curl_setopt($process, CURLOPT_COOKIEFILE, $this->cookie_file);
curl_setopt($process, CURLOPT_COOKIEJAR, $this->cookie_file);
curl_setopt($process, CURLOPT_ENCODING , '');
curl_setopt($process, CURLOPT_CONNECTTIMEOUT, 120);
curl_setopt($process, CURLOPT_TIMEOUT, 120);
curl_setopt($process, CURLOPT_PROXY,$this->proxy);
curl_setopt($process, CURLOPT_POSTFIELDS, $data);
curl_setopt($process, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($process, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($process, CURLOPT_POST, 1);
curl_setopt($process,CURLOPT_VERBOSE,1);
if($ssl){
curl_setopt ($process, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt ($process, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($process ,CURLOPT_CAINFO, YiiBase::getPathOfAlias('webroot').'/files/GTECyberTrustGlobalRoot.crt');
}
curl_setopt ($process, CURLOPT_HTTPHEADER, array('Expect:'));
$return = curl_exec($process);
$this->error_code = curl_getinfo($process, CURLINFO_HTTP_CODE);

Here is a working example. You should take a look a your options (reduce the number of option for test) and just set the CURLOPT_SSL_VERIFYPEER to false in order to disable the CA check.
// connect via SSL, but don't check cert
$handle=curl_init('https://www.google.com');
curl_setopt($handle, CURLOPT_VERBOSE, true);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
$content = curl_exec($handle);
echo $content; // show target page
