explode() on Japanese string

Question

I have to use the explode() function on Japanese text but it doesn\'t work.

Here is an example of what I have

$string = \'私　は　イタリア　人　です\';
$string = expl         


        

Answer 1

There are a number of characters other than simple ASCII space that can add whitespace between characters.

You could try using preg_split using \s (whitespace characters) or \b (word boundaries) as the pattern, however this may not be ideal as Japanese is almost certainly going to be encoded in a multiple-byte format.
