PHP - auto-create variables from query

I'm often doing something really dumb like..

select someField, someOtherField from somewhere
while ($rec = fetch) {
  $someField = $rec["someField"];
  $someOtherField = $rec["someOtherField"];
  do something...
}

To save the steps of pulling the variables out into variables, I use the following...

$rociResult = $dbA->query ("select someField from $table where xxx");
if (TRUE == $rociResult) {
  while ($rociRec = $dbA->fetch ($rociResult)) {
    extract($rociRec, EXTR_PREFIX_ALL, "v");
    echo $v_someField;
  }
}
