Ruia is an async web scraping micro-framework, written with asyncio and aiohttp, aims to make crawling url as convenient as possible.

Ruia is inspired by scrapy however instead of Twisted it's based entirely on asyncio and aiohttp.

It also supports various features like cookies, headers, and proxy, which makes it very useful in dealing with complex web scraping tasks.

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.
