我想使用Google AdWords API来获得月度搜索量和CPC，用于PHP的某些关键字。API本身让我很困惑，我读的文档、论坛帖子和问答越多，我就越困惑。
有人能以一种非常非常简单的方式向我解释它是如何工作的吗？并告诉我如何一步一步地设置和运行？
提前谢谢。
是的，这里有一个示例文件，用于获取关键字和卷的列表。
https://github.com/googleads/googleads-php-lib/blob/master/examples/AdWords/v201502/Optimization/GetKeywordIdeas.php
function GetKeywordIdeasExample(AdWordsUser $user) {
// Get the service, which loads the required classes.
$targetingIdeaService =
$user->GetService('TargetingIdeaService', ADWORDS_VERSION);
// Create seed keyword.
$keyword = 'mars cruise';
// Create selector.
$selector = new TargetingIdeaSelector();
$selector->requestType = 'IDEAS';
$selector->ideaType = 'KEYWORD';
$selector->requestedAttributeTypes = array('KEYWORD_TEXT', 'SEARCH_VOLUME',
'CATEGORY_PRODUCTS_AND_SERVICES');
// Create language search parameter (optional).
// The ID can be found in the documentation:
// https://developers.google.com/adwords/api/docs/appendix/languagecodes
// Note: As of v201302, only a single language parameter is allowed.
$languageParameter = new LanguageSearchParameter();
$english = new Language();
$english->id = 1000;
$languageParameter->languages = array($english);
// Create related to query search parameter.
$relatedToQuerySearchParameter = new RelatedToQuerySearchParameter();
$relatedToQuerySearchParameter->queries = array($keyword);
$selector->searchParameters[] = $relatedToQuerySearchParameter;
$selector->searchParameters[] = $languageParameter;
// Set selector paging (required by this service).
$selector->paging = new Paging(0, AdWordsConstants::RECOMMENDED_PAGE_SIZE);
do {
// Make the get request.
$page = $targetingIdeaService->get($selector);
// Display results.
if (isset($page->entries)) {
foreach ($page->entries as $targetingIdea) {
$data = MapUtils::GetMap($targetingIdea->data);
$keyword = $data['KEYWORD_TEXT']->value;
$search_volume = isset($data['SEARCH_VOLUME']->value)
? $data['SEARCH_VOLUME']->value : 0;
$categoryIds =
implode(', ', $data['CATEGORY_PRODUCTS_AND_SERVICES']->value);
printf("Keyword idea with text '%s', category IDs (%s) and average "
. "monthly search volume '%s' was found.'n",
$keyword, $categoryIds, $search_volume);
}
} else {
print "No keywords ideas were found.'n";
}
// Advance the paging index.
$selector->paging->startIndex += AdWordsConstants::RECOMMENDED_PAGE_SIZE;
} while ($page->totalNumEntries > $selector->paging->startIndex);
}
这里是使用TrafficEstimatorService的示例输出，而不是上面类似的TargetingIdeaService。
