VIM syntax highlighting 'buggy'? - php

Question

I switched from intelliJ to VIM a few days ago and I have a few problems with my syntax highlighting. I'm mainly working with php and html and in some files some of the ; are marked with a red background (maybe meaning there is an error in my syntax?). This most likely happens when the ; is followed by a comment //. I'm pretty sure there are no errors...
Also a few files do not provide php syntax highlight at all after a blockcomment /**/ until the php tag ?> gets closed.
Any idea what im missing? Also I'd appreciate suggestions on alternatives for syntax highlighting. It's hard to find useful stuff for webdev since VIM isn't that popular in that sector I guess.
Here my current vim settings:

I'd appreciate your help
Edit:
Here is the code thats causing the problems:

Try :syntax sync fromstart.
If that works, add autocmd BufEnter * :syntax sync fromstart to your .vimrc
Explanation: if the syntax highlighter does not process every line of code from the beginning, it may not receive a critical piece of information to understand what type of code it's processing. E.g., if you're in an HTML file and deep within a script tag, the syntax highlighter may not look back far enough to see the script tag and therefore processes your JS code as HTML.
