The third param. is for the 'limit', not for flags.
See the examples in the documentation.

$res=preg_split("/[a-z]../",$via,-1,PREG_SPLIT_DELIM_CAPTURE);
Yes...

Now is even more oddy...
Giving
array(4) {
  [0]=>
  string(4) "123G"
  [1]=>
  string(0) ""
  [2]=>
  string(1) "R"
  [3]=>
  string(1) "i"
}

Now I'm using the 
preg_match("/[a-z]..+/",$via,$res,PREG_OFFSET_CAPTURE);
dump($m);
giving a 

Array
(
    [0] => Array
        (
            [0] => ata
            [1] => 4
        )

)
