What’s the best way to handle web scraping with PHP these days? or How can I improve my web scraping

Web scraping php isn’t dead! Goutte + Guzzle is a killer combo. For JS, Panther is your best bet.

Proxies: Luminati or Oxylabs. Expensive, but free ones will wreck your scripts.

CAPTCHAs? Save yourself the headache and use a service. 2Captcha or DeathByCaptcha.
