@kenrichman Not seeing these errors for version 2.6.2 tested with PHPCompatibilityWP using
./vendor/bin/phpcs -p ../aceide/ --standard=PHPCompatibilityWP --extensions=php
It looks good, with some warnings up to 7.0 using
./vendor/bin/phpcs -p ../aceide/ --standard=PHPCompatibilityWP --extensions=php --runtime-set testVersion 7.0
Using 7.1+ some Warning and Errors appear (like create_function) which are going to cause issues.
