class ContentCrawler {private $config = ['max_depth' => 5,'timeout' => 30,'interval' => 1,'proxy_enabled' => true];public function crawl($sources) {// 初始化采集隊列$queue = new CrawlQueue();foreach ($sources as $source) {// 添加源到隊列$queue->add($source);while ($url = $queue->next()) {try {// 獲取內容$content = $this->fetchContent($url);// 提取數據$data = $this->extractData($content);// 下載資源$resources = $this->downloadResources($data);// 處理內容$processed = $this->processContent($data);// 保存結果$this->saveResult($url, $processed, $resources);// 控制采集間隔sleep($this->config['interval']);} catch (Exception $e) {$this->logger->error("Crawl failed for {$url}: " . $e->getMessage());continue;}}}}private function extractData($content) {$extractor = new DataExtractor();return $extractor->extract(['title' => true,'content' => true,'images' => true,'links' => true,'metadata' => true]);}
}

3. 內容處理實現

class ContentProcessor {public function process($content) {// 去除廣告$content = $this->removeAds($content);// 格式化內容$content = $this->formatContent($content);// 優化圖片$content = $this->optimizeImages($content);// 添加版權信息$content = $this->addCopyright($content);return $content;}private function formatContent($content) {$formatter = new ContentFormatter();return $formatter->format(['clean_html' => true,'normalize_spaces' => true,'fix_encoding' => true,'remove_scripts' => true]);}
}

優化策略

1. SEO優化策略

class SEOStrategy {public function generateStrategy($site) {// 分析站點特征$features = $this->analyzeSite($site);// 生成優化方案$strategy = ['keywords' => $this->planKeywords($features),'structure' => $this->planStructure($features),'links' => $this->planLinks($features)];// 驗證策略$this->validateStrategy($strategy);return $strategy;}private function planKeywords($features) {return ['primary' => $this->selectPrimaryKeywords($features),'secondary' => $this->selectSecondaryKeywords($features),'distribution' => $this->planDistribution($features)];}
}
