SSL Certificate with PHP CURL

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.

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.
