QUESTION ONE: Under the assumption that most, if not all, of the methods and their corresponding arguments that we push onto the _paq array refer, in fact, to specific Matomo methods created from PHP, why is it that the resetUserId() method not listed among the methods displayed at https://developer.matomo.org/api-reference/PHP-Piwik-Tracker
Is this an oversight, or was it done intentionally. Or, is it not even a PHP method? It is a lot confusing, for a beginner such as myself.
QUESTION TWO: In a similar light, do the setUserId() and setVisitorID() methods assign different values to the same parameter – namely, uid. Or, does the one assign a value to uid, and the other to cid?
