phpcrawl是一个爬虫/蜘蛛功能的基于php开发的框架，所以我们称它为网站或爬虫的PHP库。
<?php // It may take a whils to crawl a site ... set_time_limit(10000); // Inculde the phpcrawl-mainclass include("libs/PHPCrawler.class.php"); // Extend the class and override the handleDocumentInfo()-method class MyCrawler extends PHPCrawler { function handleDocumentInfo($DocInfo) { // Just detect linebreak for output ("\n" in CLI-mode, otherwise "<br>"). if (PHP_SAPI == "cli") $lb = "\n"; else $lb = "<br />"; // Print the URL and the HTTP-status-Code echo "Page requested: ".$DocInfo->url."
