怎么将中文字符串分割成单个字符

【求助】 如何将中文字符串分割成单个字符

PHP code

 $county="大中华区";  echo "<font color='red'>".$ci=iconv_strlen($county,"UTF-8")."</font>";         for($j=0;$j<$ci;$j++){            echo  $e.=iconv_substr($county,$j,$j); }

PHP code

<?php/**************************** * subCNchar() 截取汉字 * * [$str]     [要截取的字符串] * [$start]   [截取的起始位置] * [$length]  [要截取的长度] * [$charset] [字符串编码] ****************************/function subCNchar($str, $start = 0, $length, $charset = "utf-8") {    if (strlen($str) <= $length)        return $str;    $re['utf-8'] = "/[\x01-\x7f]|[\xc2-\xdf][\x80-\xbf]|[\xe0-\xef][\x80-\xbf]{2}|[\xf0-\xff][\x80-\xbf]{3}/";    $re['gb2312'] = "/[\x01-\x7f]|[\xb0-\xf7][\xa0-\xfe]/";    $re['gbk'] = "/[\x01-\x7f]|[\x81-\xfe][\x40-\xfe]/";    $re['big5'] = "/[\x01-\x7f]|[\x81-\xfe]([\x40-\x7e]|\xa1-\xfe])/";    preg_match_all($re[$charset], $str, $match);    $slice = join("", array_slice($match[0], $start, $length));    return $slice;}$county="大中华区";$res=subCNchar($county,0,1);echo $res;#大 ?>
