| All reservations are case-insensitive. |

==== void ==== | ==== void ==== |

The ''void'' name (in any combination of case) should be reserved in class, interface and trait name contexts, because this is a likely candidate for the demarcation of void functions (which do not return a value). Alternatively ''null'' can be used for this purpose, which is already reserved. However both possibilities should be kept open until we reach a decision on this question. | **Where**: As the last segment of a class, interface or trait name. As such the names ''Void'' and ''Foo\Bar\Void'' are reserved, while ''Foo\Bar\MyVoid'' and ''Void\Foo\Bar'' are okay. |

The ''enum'' name (in any combination of case) should be reserved in all contexts that are not protected by the [[https://wiki.php.net/rfc/context_sensitive_lexer|context sensitivity RFC]]. There already is an [[https://wiki.php.net/rfc/enum|enum RFC]] which will be proposed for PHP 7.x and requires this reserved keyword. | **Where**: In any context which is not protected by the [[https://wiki.php.net/rfc/context_sensitive_lexer|context sensitivity RFC]]. This includes any segment of class, interface, trait and function names. |
