I've been doing PHP for 4 years now. 2 years at school and 2 years at work.But I feel like I'm stagnating. Here are some things that I currently know about PHP:Basics (variables, control structures, arrays, loops, sessions, cookies, file manipulation)Database Integration (MySQL)OOP - I only know of the basics (creating classes, inheritance, objects, private, public and protected class variables)MVCA few frameworks (CodeIgniter, Laravel) PHPUnit (Assertions)Templating (Smarty)Using PHP with AJAXBuilding Wordpress pluginsAPI IntegrationThat's pretty much it. My question is what's next? What do I do to level up my skills as a PHP developer. What are the things that you can recommend that I would do in order to improve (Books, tutorials, etc.). What other PHP tools you can recommend that I should try and use.Thanks in advance!
