Сохраните выходные данные таблиц Google в массиве, чтобы использовать их для диаграмм Google.

Question

Я хочу прочитать онлайн-файл электронной таблицы Google, а затем хочу сохранить выходные данные в массив для создания диаграмм Google. Мне нужно сохранить результат вывода php shell_exec в массиве, чтобы использовать его для диаграмм Google. Я приложил выходные результаты в изображении.

В quickstart.php (из API таблиц Google):

  <?php
require __DIR__ . '/vendor/autoload.php';

if (php_sapi_name() != 'cli') {
    throw new Exception('This application must be run on the command line.');
}

/**
 * Returns an authorized API client.
 * @return Google_Client the authorized client object
 */
function getClient()
{
    $client = new Google_Client();
    $client->setApplicationName('Google Sheets API PHP Quickstart');
    $client->setScopes(Google_Service_Sheets::SPREADSHEETS_READONLY);
    $client->setAuthConfig('credentials.json');
    $client->setAccessType('offline');
    $client->setPrompt('select_account consent');

    // Load previously authorized token from a file, if it exists.
    // The file token.json stores the user's access and refresh tokens, and is
    // created automatically when the authorization flow completes for the first
    // time.
    $tokenPath = 'token.json';
    if (file_exists($tokenPath)) {
        $accessToken = json_decode(file_get_contents($tokenPath), true);
        $client->setAccessToken($accessToken);
    }

    // If there is no previous token or it's expired.
    if ($client->isAccessTokenExpired()) {
        // Refresh the token if possible, else fetch a new one.
        if ($client->getRefreshToken()) {
            $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        } else {
            // Request authorization from the user.
            $authUrl = $client->createAuthUrl();
            printf("Open the following link in your browser:\n%s\n", $authUrl);
            print 'Enter verification code: ';
            $authCode = trim(fgets(STDIN));

            // Exchange authorization code for an access token.
            $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
            $client->setAccessToken($accessToken);

            // Check to see if there was an error.
            if (array_key_exists('error', $accessToken)) {
                throw new Exception(join(', ', $accessToken));
            }
        }
        // Save the token to a file.
        if (!file_exists(dirname($tokenPath))) {
            mkdir(dirname($tokenPath), 0700, true);
        }
        file_put_contents($tokenPath, json_encode($client->getAccessToken()));
    }
    return $client;
}


// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Sheets($client);

// Prints the names and majors of students in a sample spreadsheet:


// https://docs.google.com/spreadsheets/d/1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms/edit
$spreadsheetId = '1cG8M5jcMeFxt31MI7-7n8xM-wktyGhxAtaZSQ67rfm8';
$range = 'Class Data!A1:B10';
$response = $service->spreadsheets_values->get($spreadsheetId, $range);
$values = $response->getValues();






if (empty($values)) {
    print "No data found.\n";
} else {
    //print "Men, Women:\n";

    foreach ($values as $row)  {
        //for($i=0; $i<=count($row)-1; $i++) {
        // Print columns A and E, which correspond to indices 0 and 4.

        echo $row[0].' '.$row[1].'<br/>';


        //}
    }
}

В отдельном php-файле я запускаю:

    $output = shell_exec('php quickstart.php');

 <script type='text/javascript'>

      // Load the Visualization API and the corechart package.
      google.charts.load('current', {'packages':['corechart']});

      // Set a callback to run when the Google Visualization API is loaded.
      google.charts.setOnLoadCallback(drawChart);

      // Callback that creates and populates a data table,
      // instantiates the pie chart, passes in the data and
      // draws it.
      function drawChart() {

        // Create the data table.
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Topping');
        data.addColumn('number', 'Slices');
        data.addRows([['column', 33],
                      ['column', 22]
]);

        // Set chart options
        var options = {'title':'How Much Pizza I Ate Last Night',
                       'width':800,
                       'height':500};

        // Instantiate and draw our chart, passing in some options.
        var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
        chart.draw(data, options);
      }
    </script>
