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.

Dude (dude uncomplicated data extraction) is a very simple framework for writing web scrapers using Python decorators. The design, inspired by Flask, was to easily build a web scraper in just a few lines of code. Dude has an easy-to-learn syntax.

The simplest web scraper will look like this:

from dude import select


@select(css="a")
def get_link(element):
    return {"url": element.get_attribute("href")}

dude supports multiple parser backends: - playwright
- lxml
- parsel - beautifulsoup - pyppeteer - selenium

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,
        ]);
    }
}
from dude import select

"""
This example demonstrates how to use Parsel + async HTTPX
To access an attribute, use:
    selector.attrib["href"]
You can also access an attribute using the ::attr(name) pseudo-element, for example "a::attr(href)", then:
    selector.get()
To get the text, use ::text pseudo-element, then:
    selector.get()
"""


@select(css="a.url", priority=2)
async def result_url(selector):
    return {"url": selector.attrib["href"]}


# Option to get url using ::attr(name) pseudo-element
@select(css="a.url::attr(href)", priority=2)
async def result_url2(selector):
    return {"url2": selector.get()}


@select(css=".title::text", priority=1)
async def result_title(selector):
    return {"title": selector.get()}


@select(css=".description::text", priority=0)
async def result_description(selector):
    return {"description": selector.get()}


if __name__ == "__main__":
    import dude

    dude.run(urls=["https://dude.ron.sh"], parser="parsel")
