composer install

If you are using macOS and are using an older version of patch, you may have problems with patch application failure during composer install. Try using brew install gpatch to install a newer and supported patch version.

PHPStan's source code is developed on PHP 8.2. For distribution in phpstan/phpstan package and as a PHAR file, the source code is transformed to run on PHP 7.2 and higher.

Initially you need to run composer install in case you aren't working in a directory which was built before.

Afterward you can run the whole build including linting and coding standards:

make

You can also choose to run only part of the build. To analyse PHPStan by PHPStan itself, run:

make phpstan

To detect code style issues, run:

make cs

And then to fix code style, run:

make cs-fix

Run:

make tests

1. Make sure Xdebug is installed and configured.
2. Add --xdebug option when running PHPStan. Without it PHPStan turns the debugger off at runtime.
3. If you're not debugging the result cache, also add the --debug option.
