SSL Certificate with PHP CURL - php

Question

I'm using curl to send an xml file over https to the rightmove API - they supplied me with all the certificates.
I am getting the error :
60SSL certificate problem: unable to get local issuer
certificateResult =
I have tried everything i have found on every other stackoverflow post similar and nothing is working, i have tried downloading the old cacert.pem and changed the files in php.ini - ive installed my personal information file andcreated a certificate on the browser and local machine and nothing is removing the error 60.
This is my PHP :
<?php
$xml = file_get_contents("myxml.xml");
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt ($ch, CURLOPT_CAINFO, dirname(__FILE__).'\mypem.pem');
curl_setopt($ch, CURLOPT_URL, "https://adfapi.adftest.rightmove.com/v1/property/sendpropertydetails");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_REFERER, 'https://adfapi.adftest.rightmove.com/v1/property/sendpropertydetails');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_VERBOSE , 1);
$ch_result = curl_exec($ch);
print curl_errno($ch);
print curl_error($ch);
echo "Result = ".$ch_result;
curl_close($ch);
?>
this has had me banging my head for days, i would be very grateful for any assistance.

Answer 1

For my particular case i needed to add the keyfile, sslcert and cert password.
//$xml = file_get_contents("thexmlfile.xml");
$xml= $propertyXml->asXML();
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_CAINFO, getcwd() . '\pemfile.pem');
curl_setopt($ch, CURLOPT_URL, "https://adfapi.adftest.rightmove.com/v1/property/sendpropertydetails");
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSH_PRIVATE_KEYFILE, getcwd() . '\myjks.jks');
curl_setopt($ch, CURLOPT_SSLCERT, getcwd() . '\pemfile.pem');
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, "thesslpassword");
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_REFERER, "https://adfapi.adftest.rightmove.com/v1/property/sendpropertydetails");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_VERBOSE , 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$ch_result = curl_exec($ch);
print curl_errno($ch);
print curl_error($ch);
echo "Result = ".$ch_result;
curl_close($ch);

Answer 2

It is failing as curl is unable to verify the certificate provided by the server.
There are two options to get this to work:
1 Allows curl to make insecure connections, that is curl does not verify the certificate.
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
2 Add the root CA (the CA signing the server certificate) in php.ini
curl.cainfo=/path/to/cacert.pem
You should use option 2 as thats the option that ensures that you are connecting to secure ftp server.

Answer 3

I was getting the same "SSL certificate problem: unable to get local issuer certificateResult" error with HTTP GET to a remote https site. I only needed to provide the CA cert to php curl, ie CURLOPT_CAINFO:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CAINFO, "/path/to/CA_Bundle.crt");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$output = curl_exec($ch);
if (curl_errno($ch)) {
$error_msg = curl_error($ch);
print "curl_error: $error_msg <br>";
} else {
print "output: $output<br>";
}
curl_close($ch);
