Wordwrap with UTF-8 supports, returns as array.

<?php

function mb_wordwrap_array($string, $width)
{
    if (($len = mb_strlen($string, 'UTF-8')) <= $width)
    {
        return array($string);
    }

    $return = array();
    $last_space = FALSE;
    $i = 0;

    do
    {
        if (mb_substr($string, $i, 1, 'UTF-8') == ' ')
        {
            $last_space = $i;
        }

        if ($i > $width)
        {
            $last_space = ($last_space == 0) ? $width : $last_space;
    
            $return[] = trim(mb_substr($string, 0, $last_space, 'UTF-8'));
            $string = mb_substr($string, $last_space, $len, 'UTF-8');
            $len = mb_strlen($string, 'UTF-8');
            $i = 0;
        }

        $i++;
    }
    while ($i < $len);

    $return[] = trim($string);

    return $return;
