Fatal error: Call to undefined method

Has your PHP installation been compiled with cURL support?

Yes cURL is working fine, even testing with the following script.

<?php

// Script to test if the CURL extension is installed on this server

// Define function to test

function _is_curl_installed() {

    if  (in_array  ('curl', get_loaded_extensions())) {

        return true;

    }

    else {

        return false;

    }

}

// Ouput text to user based on test

if (_is_curl_installed()) {

  echo "cURL is <span style="color:blue">installed</span> on this server";

} else {

  echo "cURL is NOT <span style="color:red">installed</span> on this server";

}

?>

Gives the following "cURL is installed on this server".

Which version of cURL and PHP are you using please?

Hi James,

To authenticate the user you should be using :

$sdk->platform()->login('USERNAME', 'EXT', 'PASS');

Do you have composer installed ? If so, have you provided the appropriate path for the composer's autoloader.

For a simpler understanding, take a look at the "develop" branch on our official PHP-SDK repository on github titled "How to Demo" once you have installed the SDK using either composer/PHAR:
https://github.com/ringcentral/ringcentral-php/tree/develop#how-to-demo

Hi PHP version is 5.5.9 cURL is 7.30.0...

I've now got it working, it seems to be a problem with the test server having a self signed certificate, I was using $sdk->getPlatform()->login('USERNAME', 'EXT', 'PASS'); as its what was originally detailed on the github page... 

Thanks

Yes, I too have had issues with self-signed certificates. If you just need a quick place to test that is not on your local machine, you can use Heroku (they support PHP) since the URL they provide you has a valid certificate chain available. Azure and GCP may also provide this feature, but I've not tested in those environments.
