[TYPO3-mvc] Strange usage of array_fill_keys()

[Stefan Neufeind]

Hi,

during review of a patch I stumbled across something I couldn't make
sense of. And the comment seems to indicate somebody else had the same
problem :-)
in Typo3DbBackend.php, getRowsFromResult() is just:

  $rows = array();
  while ($row = $this->databaseHandle->sql_fetch_assoc($result)) {
    if (is_array($row)) {
      // TODO Check if this is necessary, maybe the last line is enough
      $arrayKeys = range(0, count($row));
      array_fill_keys($arrayKeys, $row);
      $rows[] = $row;
    }
  }
  return $rows;

@Jochen/Sebastian: Git says you were somehow involved in those two
lines. What is actually their background/use-case? If they are needed,
could we come up with a testcase for one special problem you adressed
this way?

In case it makes sense in some way (which I'm not really sure yet) the
arrayKeys-array is one element too long. But practically that seems to
be of no importance.


Kind regards,
 Stefan
