Could anybody explain, why this code $string=’6аd_ТЕХТ GOOD_TEXT’; $words = preg_split(‘/\s+/’, $string, NULL, PREG_SPLIT_NO_EMPTY);

Could anybody explain, why this code

$string='6аd_ТЕХТ GOOD_TEXT';
$words = preg_split('/\s+/', $string, NULL, PREG_SPLIT_NO_EMPTY);

var_dump($words);

displays

array(2) { [0]=> string(8) "6àd_ÒÅÕÒ" [1]=> string(9) "GOOD_TEXT" }

instead of 

array(2) { [0]=> string(8) "6аd_ТЕХТ" [1]=> string(9) "GOOD_TEXT" }

I’ve read about this issue, but adding /u :

preg_split('/\s+/', $string, NULL, PREG_SPLIT_NO_EMPTY);// '/\s+/'

to become

preg_split('/\s+/u', $string, NULL, PREG_SPLIT_NO_EMPTY);// '/\s+/u'

doesn’t help.
How to fix this issue?

Thank you.

    There is something else happening in your code that isn’t present in the provided example. Tested the provided example and it works as expected. On the off-chance that this is really happening (and there is no other code affecting $string), this may be a bug with the specific PHP version you’re using and can be solved by upgrading PHP (but it’s highly unlikely that it’s an issue with PHP).
