At the recent years, I used a lot PHP to develop my web crawlers and save my life to make some duplicated works automated.
I also research them and write a book (it's written in Mandarin). And the book link is available here: https://www.books.com.tw/products/0010882656
This book tile translates to English is: PHP Web Crawler Development:From beginner to advanced web crawler technique guides.
In this session, I will present following topics:
