This PR is part of the preparation for PHPCS 3.x compatibility.
The
removeTokenListener()
method was used to prevent the sniffs using these abstracts from being called for further files, however, this method will no longer exist in PHPCS 3.x with no alternative.The
AbstractFunctionRestrictionSniff
also uses agetGroups()
method, but calls it earlier and prevents the child sniffs from being run without groups by just not registering any token listeners if no groups are found.This same methodology has now been implemented in the two abstracts which used the
removeTokenListener()
method, effectively making these sniffs more efficient and preventing the removal of the method from becoming a problem.
