What resources or references would you recommend for someone looking to improve their PHP skills and understanding of best practices?

To improve PHP skills and understanding of best practices, I recommend utilizing online resources such as the official PHP documentation, online tutorials on websites like W3Schools and PHP.net, and books like "PHP Objects, Patterns, and Practice" by Matt Zandstra. Additionally, joining online communities like Stack Overflow or PHP forums can provide valuable insights and feedback from experienced developers.
