Answer 1

You need to specify the Unicode modifier u to get Unicode character properties in PCRE.

For example...

$pattern = "/([\p{L}]+)/u";
$string  = "你好，世界！Привет мир! !مرحبا بالعالم";
if (preg_match_all($pattern, $string, $match)) {
    var_dump($match);
}

Gives us...

array(2) {
  [0]=>
  array(6) {
    [0]=>
    string(6) "你好"
    [1]=>
    string(6) "世界"
    [2]=>
    string(12) "Привет"
    [3]=>
    string(6) "мир"
    [4]=>
    string(10) "مرحبا"
    [5]=>
    string(14) "بالعالم"
  }
  [1]=>
  array(6) {
    [0]=>
    string(6) "你好"
    [1]=>
    string(6) "世界"
    [2]=>
    string(12) "Привет"
    [3]=>
    string(6) "мир"
    [4]=>
    string(10) "مرحبا"
    [5]=>
    string(14) "بالعالم"
  }
}
