<?php
  public function generator($data) {
    if ($data) {
      if ($u = array_pop($data)) {

Avoid variables with short names like $u. Configured minimum length is 3.

        foreach ($this->generator($data) as $p) {
          foreach ($u as $v) {
            yield $p + [count($p) => $v];
          }
        }
      }
    }
    else {
      yield [];
    }
