Roach is a complete web scraping toolkit for PHP. It is heavily inspired by the popular Scrapy package for Python.

Roach allows us to define spiders that crawl and scrape web documents. Roach isn’t just a simple crawler, but includes an entire pipeline to clean, persist and otherwise process extracted data as well.

Just like scrapy, Roach supports: - Middlewares - Item Pipelines - Extendibility through Plugins

It’s your all-in-one resource for web scraping in PHP.

Spidr is a Ruby gem that provides a simple and flexible way to spider and scrape websites. It allows you to easily navigate through a website, following links and scraping data as you go. It is built on top of Nokogiri, a popular Ruby gem for parsing and searching HTML and XML documents, and it provides a simple and intuitive API for defining and running web scraping operations.

One of the main features of Spidr is its ability to spider a website, following all the links on a page and visiting all the pages of a website. This allows you to easily and quickly scrape large amounts of data from a website, without having to manually specify which pages to visit.

In addition to its spidering capabilities, Spidr also provides a variety of other features that can simplify the web scraping process. It can automatically filter which links to follow and which pages to visit, it can handle cookies and authentication, and it can automatically store the scraped data in a database or file. It also provides a built-in support for parallelism and queueing to speed up the scraping process.

Example Use


<?php

use RoachPHP\Http\Response;
use RoachPHP\Spider\BasicSpider;

class RoachDocsSpider extends BasicSpider
{
    /**
     * @var string[]
     */
    public array $startUrls = [
        'https://roach-php.dev/docs/spiders'
    ];

    public function parse(Response $response): \Generator
    {
        $title = $response->filter('h1')->text();

        $subtitle = $response
            ->filter('main > div:nth-child(2) p:first-of-type')
            ->text();

        yield $this->item([
            'title' => $title,
            'subtitle' => $subtitle,
        ]);
    }
}
require 'spidr'

Spidr.start_at("http://example.com") do |spider|
  spider.every_page do |page|
    puts "Visiting: #{page.url}"

    # Extract data from the page using Nokogiri
    doc = Nokogiri::HTML(page.body)
    title = doc.css("title").text
    puts "Title: #{title}"
  end
end
