I’m trying to get words from string in php using preg_split like this:

$result = preg_split('/[^A-Za-z]+/', $text)

but this doesn’t work, some words are split,
what am I doing wrong?

Edit: the fact is it doesn’t work with russian text = “фыва ывафы фываф”;

$result = preg_split('/[^А-яа-я]+/', $text)

    [^A-Za-z] only takes ASCII letters into account. You need to split on Unicode non-letters:

    $result = preg_split('/\P{L}+/u', $subject);

    [^А-Яа-я]+ won’t work either because in the Unicode character set, А (0x0410) is not the first Kyrillian letter, and я (0x044F) is not the last one. It appears these honors go to Ё (0x0401) and ӹ (0x04F9). I don’t know Russian at all, so I can’t speculate on why this is so.

    You can check this easily using your character map program:
