Web crawlers, web bots, scrapping and PHP by Peter

Back to 2014, I create my first web bot via PHP/cURL to login WiFi automatically.
Nowadays, I create lots of the web bots and crawlers to complete my side projects and services.
In this session, I will present how to use the existing/correct PHP packages to accomplish a web bot and crawler.
And present some approaches/tips about fetching current contents on specific website.
