PHP Working Example of TrafficEstimatorService v201109

[Yakito]

Hello,
I am new to the AdWords API and I am trying to understand how to use
the different services. I am having problems with the
TrafficEstimatorService as there is no example in the current version
of the PHP API. When I try to use the previous version API I get some
error with the class "CountryTarget()" that does not exists in the
current version.

This is the code I am testing:

$path = dirname(__FILE__) . '/../../../src';
set_include_path(get_include_path() . PATH_SEPARATOR . $path);

require_once 'Google/Api/Ads/AdWords/Lib/AdWordsUser.php';
require_once 'Google/Api/Ads/Common/Util/MapUtils.php';

// Constants used in the example.
define('PAGE_SIZE', 500);
/**
 * Runs the example.
 * @param AdWordsUser $user the user to run the example with
 */
function GetKeywordIdeasExample(AdWordsUser $user) {
  // Get the service, which loads the required classes.
  $targetingIdeaService = $user->GetService('TrafficEstimatorService',
'v201109');
  $keywords = array();
  $keywords[] = new Keyword('mars cruise', 'BROAD');
  $keywords[] = new Keyword('cheap cruise', 'PHRASE');
  $keywords[] = new Keyword('cruise', 'EXACT');

  // Create a keyword estimate request for each keyword.
  $keywordEstimateRequests = array();
  foreach ($keywords as $keyword) {
    $keywordEstimateRequest = new KeywordEstimateRequest();
    $keywordEstimateRequest->keyword = $keyword;
    $keywordEstimateRequests[] = $keywordEstimateRequest;
  }

  // Create ad group estimate requests.
  $adGroupEstimateRequest = new AdGroupEstimateRequest();
  $adGroupEstimateRequest->keywordEstimateRequests =
$keywordEstimateRequests;
  $adGroupEstimateRequest->maxCpc = new Money(1000000);
  $adGroupEstimateRequests = array($adGroupEstimateRequest);

  // Create campaign estimate requests.
  $campaignEstimateRequest = new CampaignEstimateRequest();
  $campaignEstimateRequest->adGroupEstimateRequests =
$adGroupEstimateRequests;
  $campaignEstimateRequest->targets = array(new CountryTarget('US'),
      new LanguageTarget('en'));
  $campaignEstimateRequests = array($campaignEstimateRequest);

  // Create selector.
  $selector = new TrafficEstimatorSelector();
  $selector->campaignEstimateRequests = $campaignEstimateRequests;

  // Get traffic estimates.
  $result = $trafficEstimatorService->get($selector);

  // Display traffic estimates.
  if (isset($result)) {
    $keywordEstimates =
        $result->campaignEstimates[0]->adGroupEstimates[0]-
>keywordEstimates;
    for ($i = 0; $i < sizeof($keywordEstimates); $i++) {
      $keyword = $keywordEstimateRequests[$i]->keyword;
      $keywordEstimate = $keywordEstimates[$i];

      // Find the mean of the min and max values.
      $meanAverageCpc = ($keywordEstimate->min->averageCpc-
>microAmount
          + $keywordEstimate->max->averageCpc->microAmount) / 2;
      $meanAveragePosition = ($keywordEstimate->min->averagePosition
          + $keywordEstimate->max->averagePosition) / 2;
      $meanClicks = ($keywordEstimate->min->clicks
          + $keywordEstimate->max->clicks) / 2;
      $meanTotalCost = ($keywordEstimate->min->totalCost->microAmount
          + $keywordEstimate->max->totalCost->microAmount) / 2;

      printf("Results for the keyword with text '%s' and match type
'%s':\n",
          $keyword->text, $keyword->matchType);
      printf("  Estimated average CPC: %.0f\n", $meanAverageCpc);
      printf("  Estimated ad position: %.2f \n",
$meanAveragePosition);
      printf("  Estimated daily clicks: %d\n", $meanClicks);
      printf("  Estimated daily cost: %.0f\n\n", $meanTotalCost);
    }
  } else {
    print "No traffic estimates were returned.\n";
  }
}



try {
  // Get AdWordsUser from credentials in "../auth.ini"
  // relative to the AdWordsUser.php file's directory.
  $user = new AdWordsUser();

  // Log every SOAP XML request and response.
  $user->LogAll();

  // Run the example.
  GetKeywordIdeasExample($user);
} catch (Exception $e) {
  printf("An error has occurred: %s\n", $e->getMessage());
}

The error is on line 72, but remember thats an example from a previous
version of the API. Any tip in the right direction will be much
appreciated!

Thanks!
