Crawl all internal links found on a website

Crawl the web using PHP

This package provides a powerful, easy to use class to crawl links on a website. Under the hood, Guzzle promises are used to crawl multiple URLs concurrently.

Because the crawler can execute JavaScript, it can crawl JavaScript rendered sites. Under the hood, Chrome and Puppeteer are used to power this feature.

Here's a quick example:

use Spatie\Crawler\Crawler;
use Spatie\Crawler\CrawlResponse;

Crawler::create('https://example.com')
    ->onCrawled(function (string $url, CrawlResponse $response) {
        echo "{$url}: {$response->status()}\n";
    })
    ->start();

Or collect all URLs on a site:

$urls = Crawler::create('https://example.com')
    ->internalOnly()
    ->depth(3)
    ->foundUrls();

You can also test your crawl logic without making real HTTP requests:

Crawler::create('https://example.com')
    ->fake([
        'https://example.com' => '<html><a href="/about">About</a></html>',
        'https://example.com/about' => '<html>About page</html>',
    ])
    ->foundUrls();

If you need to stop a crawl based on external state, you can register a callback that receives the current crawler instance and is checked before scheduling each next request:

use Spatie\Crawler\Crawler;

$shouldStop = false;

Crawler::create('https://example.com')
    ->shouldStopCallback(function (Crawler $crawler) use (&$shouldStop) {
        return $shouldStop;
    })
    ->onCrawled(function (string $url) use (&$shouldStop) {
        $shouldStop = true;
    })
    ->start();
