Its been 2 years since ive touched php. I still know the basics but if anyone can help me with pocket-mine because i am lost. Its a lot different than it was 2 years ago.
The API has not changed, it is different. this means that you may not have touched for 2 years, but you are able to identify the functions because it has always been the same logic. more pocketmine you but has a doxygen library at your disposal https://jenkins.pmmp.io/job/PocketMine-MP-doc/doxygen/ So it's a forum to help, not to learn.
Use PHPStorm and install the PMMP library into it. Then you will learn along making some new projects, as PHPStorm really helps. You have a month trial to learn so xD
