支持中文的PHP按字符串长度分割成数组代码

以下是我编写的代码,实现对中英文混杂字符进行分割

  <?php  function mbStrSplit ($string, $len=1) {    $start = 0;    $strlen = mb_strlen($string);    while ($strlen) {      $array[] = mb_substr($string,$start,$len,"utf8");      $string = mb_substr($string, $len, $strlen,"utf8");      $strlen = mb_strlen($string);    }    return $array;  }    header('Content-type:text/html;charset=utf-8');  $str = '我爱北京3我爱上海-我爱xianggang';  $r = mbStrSplit($str, 4);  echo '<pre>';  print_r($r);  echo '</pre>';  ?>    

运行结果:

  Array  (    [0] => 我爱北京    [1] => 3我爱上    [2] => 海-我爱    [3] => xian    [4] => ggan    [5] => g  )    

  <?php   function str_split_unicode($str, $l = 0) {   if ($l > 0) {   $ret = array();   $len = mb_strlen($str,"UTF-8");   for ($i = 0; $i < $len; $i += $l) {   $ret[] = mb_substr($str, $i, $l,"UTF-8");  }   return $ret;  }   return preg_split("//u", $str, -1, PREG_SPLIT_NO_EMPTY);  }  ?>   $s ="还未如愿sss见gfg者不rtret不朽"; // Mild milk   print_r(str_split($s, 5));   print_r(str_split_unicode($s, 5));    //输出   //Array ( [0] => 还�� [1] => �如� [2] => ��sss [3] => 见gf [4] => g者� [5] => ��rtr [6] => et不 [7] => 朽 )   //Array ( [0] => 还未如愿s [1] => ss见gf [2] => g者不rt [3] => ret不朽 )
