<![CDATA[
|
|
All globals terms must be prefixed with a theme/plugin specific term. Global terms include Namespace names, Class/Interface/Trait/Enum names (when not namespaced), Functions (when not namespaced or in an OO structure), Constants/Variable names declared in the global namespace, and Hook names.
|
|
|
|
A prefix must be distinct and unique to the plugin/theme, in order to prevent potential conflicts with other plugins/themes and with WordPress itself.
|
|
|
|
The prefix used for a plugin/theme may be chosen by the developers and should be defined in a custom PHPCS ruleset to allow for this sniff to verify that the prefix is consistently used.
|
|
Prefixes will be treated in a case-insensitive manner.
