Problem description

I have configured a custom ruleset and it is not getting used.

Steps to reproduce

Steps to reproduce the behavior:

1. Add configuration to init.el

(use-package flycheck
  :ensure t
  :diminish flycheck-mode
  :custom
  (flycheck-php-executable "/usr/bin/php")
  (flycheck-phpcs-executable "/usr/local/bin/phpcs")
  (flycheck-phpcs-standard "/usr/local/bin/.phpcs.xml")
  (flycheck-phpmd-executable "/usr/local/bin/phpmd")
  :init (global-flycheck-mode))
(add-hook 'after-init-hook #'global-flycheck-mode)

3. Create /usr/local/bin/.phpcs.xml

<?xml version="1.0"?>
<ruleset name="SERStandard">
    <description>My custom coding standard.</description>
    <rule ref="PEAR">
        <exclude name="PEAR.NamingConventions.ValidFunctionName.PrivateNoUndescore" />
    </rule>
</ruleset>

4. See error
   PEAR.NamingConventions.ValidFunctionName error still occurs in mini buffer window

• I have read https://emacs.stackexchange.com/questions/28429/how-do-i-troubleshoot-emacs-problems

Expected behavior

A clear and concise description of what you expected to happen.
The rule should no longer be enforced so this error should not be displayed in the minibuffer

Screenshots

If applicable, add screenshots to help explain your problem.

System configuration

Syntax checkers for buffer AlphaCharacterState.php in php-mode:

First checker to run:

  php
    - may enable:    yes
    - executable:    Found at /usr/bin/php
    - next checkers: php-phpmd, php-phpcs

Checkers that may run as part of the first checker's chain:

  php-phpmd
    - may enable:    yes
    - executable:    Found at /usr/local/bin/phpmd
    - next checkers: php-phpcs

  php-phpcs
    - may enable: yes
    - may run:    t
    - executable: Found at /usr/local/bin/phpcs

Flycheck Mode is enabled.  Use C-u C-c ! x to enable disabled
checkers.
