Google People API | Extract email addresses from response | PHP

Question

I'm exploring the Google People API to get emails of contacts of authenticated users. The code below works perfectly fine for getting the contacts information from Google. I'm able to extract the display names as well by using the function getDisplayName().

However I'm unable to extract the emails address from the response. When I print the response from Google I can see the email addresses but I'm unable to extract it. Any assistance will be helpful.

Pease see the code below:



//Include Configuration File
include('config.php');

//print_r($client);
$login_button = '';

//This $_GET["code"] variable value received after user has login into their Google Account redirct to PHP script then this variable value has been received
if(isset($_GET["code"]))
{
 //It will Attempt to exchange a code for an valid authentication token.
 $token = $client->fetchAccessTokenWithAuthCode($_GET["code"]);

 //This condition will check there is any error occur during geting authentication token. If there is no any error occur then it will execute if block of code/
  if(!isset($token['error']))
  {
    //Set the access token used for requests
    $client->setAccessToken($token['access_token']);

    //Store "access_token" value in $_SESSION variable for future use.
    $_SESSION['access_token'] = $token['access_token'];

    // GET CONTACTS USING token

    // $client=getClient();
    $service = new Google_Service_PeopleService($client);

    $optParams = array('personFields' => 'names,emailAddresses');
    $results = $service->people_connections->listPeopleConnections('people/me', $optParams);
    // print_r($results);
    if (count($results->getConnections()) == 0)
    {
      print "No connections found.\n";
    }else
    {
      print "People:\n";
      $i=1;
      foreach ($results->getConnections() as $person)
      {
        if (count($person->getNames()) == 0)
        {
          print "No names found for this connection\n";
        }else
        {
          $names = $person->getNames();
          $name = $names[0];
          echo $i;
          printf("%s\n", $name->getDisplayName());

          $email_ids = $person->getemailAddresses(); 
          $email_id = $email_ids[0];
          printf("%s\n", $email_id->getValue()); //THIS IS WHERE THE ERROR HAPPENS AND I'M UNABLE TO 
 //DETERMINE THE RIGHT FUNCTION

        }
        echo "<br><br>";
        $i++;
      }
    }
  }
}

//This is for check user has login into system by using Google account, if User not login into system then it will execute if block of code and make code for display Login link for Login using Google account.

 //Create a URL to obtain user authorization
 $login_button = '<a href="'.$client->createAuthUrl().'"><img src="https://i.stack.imgur.com/mGHPI.png" /></a>';

The output of the code is

It does display the first name and runs into the below error: Fatal error: Uncaught Error: Call to a member function getValue() on null in C:\xampp\htdocs\googlecontacts\index.php:57 Stack trace: #0 {main} thrown in C:\xampp\htdocs\googlecontacts\index.php on line 57 — adarsh405, May 08 '21 at 21:53
This part of the code doesnt do anything and can be ignored: $email_ids = $person->getemailAddresses(); $email_id = $email_ids[0]; — adarsh405, May 09 '21 at 01:18
