Gerapy is a Distributed Crawler Management Framework Based on Scrapy, Scrapyd, Scrapyd-Client, Scrapyd-API, Django and Vue.js.

It is built on top of the Scrapy framework and provides a simple and easy-to-use interface for performing web scraping tasks. Gerapy also includes features such as support for scheduling and distributed crawling, as well as a built-in web-based dashboard for monitoring and managing scraping tasks. Additionally, Gerapy is designed to be highly extensible, allowing users to easily create custom plugins and integrations.

Overall, Gerapy is a useful tool for those looking to automate web scraping tasks and extract data from websites.

php-spider is a PHP library for web crawling and scraping. It allows developers to easily navigate and extract data from websites by simulating a web browser's behavior.

supports two traversal algorithms: breadth-first and depth-first
supports crawl depth limiting, queue size limiting and max downloads limiting
supports adding custom URI discovery logic, based on XPath, CSS selectors, or plain old PHP
comes with a useful set of URI filters, such as Domain limiting
supports custom URI filters, both prefetch (URI) and postfetch (Resource content)
supports custom request handling logic
supports Basic, Digest and NTLM HTTP authentication. See example.
comes with a useful set of persistence handlers (memory, file)
supports custom persistence handlers
collects statistics about the crawl for reporting
dispatches useful events, allowing developers to add even more custom behavior
supports a politeness policy

This Spider does not support Javascript.

Example Use

```php use Example\StatsHandler; use VDB\Spider\Discoverer\XPathExpressionDiscoverer; use Symfony\Contracts\EventDispatcher\Event; use VDB\Spider\Event\SpiderEvents; use VDB\Spider\Spider; require_once('example_complex_bootstrap.php'); // Create Spider $spider = new Spider('http://dmoztools.net'); // Add a URI discoverer. Without it, the spider does nothing. In this case, we want tags from a certain

$spider->getDiscovererSet()->set(new XPathExpressionDiscoverer("//div[@id='catalogs']//a")); // Set some sane options for this example. In this case, we only get the first 10 items from the start page. $spider->getDiscovererSet()->maxDepth = 1; $spider->getQueueManager()->maxQueueSize = 10; // Let's add something to enable us to stop the script $spider->getDispatcher()->addListener( SpiderEvents::SPIDER_CRAWL_USER_STOPPED, function (Event $event) { echo "\nCrawl aborted by user.\n"; exit(); } ); // Add a listener to collect stats to the Spider and the QueueMananger. // There are more components that dispatch events you can use. $statsHandler = new StatsHandler(); $spider->getQueueManager()->getDispatcher()->addSubscriber($statsHandler); $spider->getDispatcher()->addSubscriber($statsHandler); // Execute crawl $spider->crawl(); // Build a report echo "\n ENQUEUED: " . count($statsHandler->getQueued()); echo "\n SKIPPED: " . count($statsHandler->getFiltered()); echo "\n FAILED: " . count($statsHandler->getFailed()); echo "\n PERSISTED: " . count($statsHandler->getPersisted()); // Finally we could do some processing on the downloaded resources // In this example, we will echo the title of all resources echo "\n\nDOWNLOADED RESOURCES: "; foreach ($spider->getDownloader()->getPersistenceHandler() as $resource) { echo "\n - " . $resource->getCrawler()->filterXpath('//title')->text(); } ```
