LinkedIn Api - Uncaught exception 'OAuthException'

I'm currently attempting to install a login button for LinkedIn onto my website. I'm trying to go step by step as the developers section shows. After I wrote the code to get a request token and checked it using print_r. 

define("my consumer key");
define("my consumer secret");

$oauth = new OAuth(my consumer key, my consumer secret);

//The first item of business is getting a request token
$request_token_response = $oauth->getRequestToken('https://api.linkedin.com/uas/oauth/requestToken');

if($request_token_response === FALSE) {
        throw new Exception("Failed fetching request token, response was:"
        . $oauth->getLastResponse());
} else {
        $request_token = $request_token_response;
}

print "Request Token:\n";
printf("    - oauth_token        = %s\n", $request_token['oauth_token']);
printf("    - oauth_token_secret = %s\n", $request_token['oauth_token_secret']);
print "\n";

I got "Fatal error:Uncaught exception 'OAuthException'...Peer certificate cannot be authenticated with known CA certificates". The line that was called for the error is below

$request_token_response = $oauth->getRequestToken('https://api.linkedin.com/uas/oauth/requestToken');

I am not understanding what that error is trying to tell me so that I can fix the problem. I would appreciate and tips or guidance to help me better understand what this error message is trying to convey and how to fix it.

It seems that the library is trying to verify the SSL certificate and it cannot do so. You could disable ssl checks via the method OAuth::disableSSLChecks. I assume you are using the following pecl extension http://www.php.net/manual/en/class.oauth.php. If not the client library you are using should have a method to disable the SSL certificate verification.

....
...
$oauth = new OAuth(my consumer key, my consumer secret);   
$oauth->disableSSLChecks();
..
...

Ideally you would do it right after instantiation
