For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 25 and the first side effect is on line 58.

It seems like abs($vote->getTimestamp() - microtime(true)) > 0.5 ? $vote->getTimestamp() + 0.001 : false can also be of type double; however, Condorcet\Vote::setRanking() does only seem to accept boolean, maybe add an additional type check?
