The scripts phpstorm-phpcbf, phpstorm-phpcs, and phpstorm-phpstan can be
used in PhpStorm if one projects contains multiple software projects with
different phpcs or phpstan configurations. The scripts look upward from the
file to analyze for an appropriate configuration file. If no configuration
file is found the scripts exit with code 0 so PhpStorm shows no error.
The actual tool to execute is searched relative to the directory of the
configuration file (see constant RELATIVE_TOOL_PATHS). If it is not
found, the fallback is used (see constant TOOL_FALLBACK).
The configuration files configured in PhpStorm are ignored.
