PHP is one of the most commonly used programming languages on the web. Many developers have a love-hate relationship with the language, despite criticism the security and performance of the language has significantly improved with PHP 7 and will continue with PHP 8. Most recently I've been reading the book Mastering PHP 7 by Branko Ajzele on PacktPub. It discusses the new and advanced features of PHP. What resources are you using to learn PHP?
