Allow in paths

You can allow some previously disallowed calls and usages using the allowIn configuration key, for example:

parameters:
    disallowedMethodCalls:
        -
            method: 'PotentiallyDangerous\Logger::log()'
            message: 'use our own logger instead'
            allowIn:
                - path/to/some/file-*.php
                - tests/*.test.php

Paths in allowIn support fnmatch() patterns.

Relative paths in allowIn are resolved based on the current working directory. When running PHPStan from a directory or subdirectory which is not your "root" directory, the paths will probably not work. Use filesRootDir in that case to specify an absolute root directory for all allowIn paths. Absolute paths might change between machines (for example your local development machine and a continuous integration machine) but you can use %rootDir% to start with PHPStan's root directory (usually /something/something/vendor/phpstan/phpstan) and then .. from there to your "root" directory.

For example when PHPStan is installed in /home/foo/vendor/phpstan/phpstan and you're using a configuration like this:

parameters:
    filesRootDir: %rootDir%/../../..
    disallowedMethodCalls:
        -
            method: 'PotentiallyDangerous\Logger::log()'
            allowIn:
                - path/to/some/file-*.php

then Logger::log() will be allowed in /home/foo/path/to/some/file-bar.php.

If you need to disallow a methods or a function call, a constant, a namespace, a class, a superglobal, or an attribute usage only in certain paths, as an inverse of allowIn, you can use allowExceptIn (or the disallowIn alias):

parameters:
    filesRootDir: %rootDir%/../../..
    disallowedMethodCalls:
        -
            method: 'PotentiallyDangerous\Logger::log()'
            allowExceptIn:
                - path/to/some/dir/*.php

This will disallow PotentiallyDangerous\Logger::log() calls in %rootDir%/../../../path/to/some/dir/*.php.

Please note that before version 2.15, filesRootDir was called allowInRootDir which is still supported, but deprecated.
