Type confusion: callback or callable

[scato]

The ABNF on http://phpdoc.org/docs/latest/references/phpdoc/types.html contains "callback" as a keyword, but not "callable". The list of keywords below contains "callable", not "callback".

http://php.net/manual/en/language.pseudo-types.php says those two are the same, a bit perhaps like "bool" and "boolean"?

I'd be happy to create a pull request for updating the reference documentation, but I have no idea where to find it. :)

Hello @scato,

IIRC the official keyword is callable as that is also used to create type hints with. A PR is greatly appreciated!

callback is an old documentation wording that predates the callable type hint and \Closure class.
