It's an error in xrange function above, when $start > $limit:
for ($i = $start; $i >= $limit; $i -= $step) {
yield $i;
}
It should be :
for ($i = $start; $i >= $limit; $i += $step) {
yield $i;
}
In this condition step MUST be negative, as result: $i -= $step increments $i, but we need decrement
it, so we need $i +=$step.
