So I have this regexp:

if (preg_match("/^(.*?)\s*(\d*?)\s*([A-Z,a-z,-]*?)$/", $search, $m)){
    $streetname = uc_words($m[1]);
    $streetnumber = trim($m[2]);
    $streetletter = strtoupper($m[3]);
    $search = trim($streetname . SPACE . $streetnumber . 
$streetletter);
}

The desired result is taki9ng the input ($search) and split it into 
its parts as an address, right? $search can be, for example, "foo 
street 34", "longstreet 45b", "longstreet 45 b" or just "longstreet".

So, if I print_r($m) with different input I get:

Array
(
    [0] => foo street 34
    [1] => foo street
    [2] => 34
    [3] => 
)
Array
(
    [0] => longstreet 45b
    [1] => longstreet
    [2] => 45
    [3] => b
)
Array
(
    [0] => longstreet 45 b
    [1] => longstreet
    [2] => 45
    [3] => b
)

You get the idea. But problems arise when I search for the streetname 
alone:

Array
(
    [0] => longstreet
    [1] => 
    [2] => 
    [3] => longstreet
)

As you can see, the last group "([A-Z,a-z,-]*?)" matches the entire 
search term since there are no digits and the first group is 
non-greedy. And if I make the first group greedy, "longstreet" is 
matched correctly, but it also catches the entire "longstreet 45b" 
when searching for that.

Also, when searching for a term in swedish characters, I get this:

Array
(
    [0] => vikavägen
    [1] => vikavä
    [2] => 
    [3] => gen
)

Which is quite odd to me, why isn't "vikavägen" matched the same 
(undesired) way that "oongstreet". I have tried the /u modifier, and 
made sure that it was utf8-encoded, but it didn't make a difference 
(incoming encoding is ISO 8859-1).

Why the difference, and how do I correctly parse out parts as needed?

Any help is appreciated.
