And of course,in production, it always reported success and never changed the password, because of equally bad server code.

in_array($this->market, ["ru"])

There is an old mysterious legend, which says that those conditions are lightening fast which are using in_array($source, ["target"]) instead of just "==". Is says always that probably you never do code refactoring, and keep all shit alive
