Basically you need to use the modifieru

option when working with unicode strings. However, the regex can also be simplified using a character class :upper:

as it will match all uppercase unicode characters.

Like this:

$string = "test sample test: 2015. ŽYDRŪNAS PAVARDENIS";

preg_match_all("/[[:upper:]]+/u", $string, $matches);
var_dump($matches);


Output:

array(1) {
  [0]=>
  array(2) {
    [0]=>
    string(10) "ŽYDRŪNAS"
    [1]=>
    string(10) "PAVARDENIS"
  }
}
