How to count # words in a textarea

Question

Question by Yuliang Han

I am wondering whether there is any javascript and PHP code to count number of words which are encoded in unicode.

Answer 1

Picked out from the php.net’s manual

function str_word_count_utf8($str) {
  return count(preg_split('~[^p{L}p{N}']+~u',$str));
}

As it is quoted

If the pattern contains utf-8, utf8_encode() the pattern,
as it is expected to be valid utf-8 (using the u modifier).
