WordPress Coding Standards are well documented in detail in WordPress Developer Handbook. WordPress also offers a Github project, which maintains the WordPress Coding Standards rules and the tools needed to inspect and format the code (PHP Code Sniffer And Beautifier).
It is to keep in mind that, WordPress Coding Standards have notable differences from PSR (PHP Standard Recommendation), for example:
- snake case (
my_function_name) - space around function arguments (
myfunction ( 'foo' )) - long array syntax (
array()instead of[]) - and more
