As a PHP developer, I should probably rejoice when someone's saying "we do microservices in PHP". I don't. I'm fine with PHP and I like microservices but the combination is just bad. PHP is a tool for solving a narrow range of tasks (i.e. making websites) and if you're trying to do something out of this range (i.e. making microservices) — you're gonna have a bad time.
In this post, I tried to collect all microservice-related PHP problems I saw over the years.
