All of us PHP developers should be very well familiar with WordPress Coding Standards for PHP_CodeSniffer (
phpcs). It automatically finds problems in WordPress code, both in terms of code style but also in terms of performance and security. It should be configured in your IDE and called in your repos’
Did you also know that PHP_CodeSniffer includes a tool called
phpcbf (PHP Code Beautifier and Fixer) that can automatically fix a lot of the issues that PHPCS discovers?
So to do an initial pass to fix a plugin’s PHP code, you can just run:
phpcbf --standard=WordPress-Core php/*.php
This is great for automating the accommodation for WordPress’s affection for whitespace 🙂
