Thank a lot for answer. I have already found the solution. Here is the source:
function DownloadAdPerformanceReport(AdWordsUser $user, $filePath,
$reportFormat) {
// Prepare a date range for the last week. Instead you can use 'LAST_7_DAYS'.
$dateRange = sprintf('%d,%d',
date('Ymd', strtotime('-1 hour')), date('Ymd', strtotime('now')));
// Create report query.
$reportQuery = 'SELECT Id, Clicks, Impressions FROM AD_PERFORMANCE_REPORT '
. 'WHERE Status IN [ENABLED, PAUSED] DURING ' . $dateRange;
// Set additional options.
$options = array('version' => ADWORDS_VERSION);
// Download report.
$result=ReportUtils::DownloadReportWithAwql($reportQuery, $filePath, $user,
$reportFormat, $options);
return $result;
