My experience included the following
- `hrtime` is used over `microtime` via a specially crafted quick selector to ensure quickest response.
- I learned and measured performance of variables, properties methods, `call_user_func` impact, static properties and static methods, magic methods `__get`, `__set`, `__call`, inheritance and all their combinations.
- Went through various lists of tips to write better PHP code. Such as this incredible example — RectorPHP ruleset https://github.com/rectorphp/rector/blo ... verview.md
- Read and learned AOP, Proxy pattern, Decorator pattern and various approaches to create `CachedImportantService class`, `Cacheable` trait and interface.
- ReactPHP looks very promising and interesting.
- PHP8 is on the way and I'll do my best so my code won't break after reading what's coming.
