支援中文的PHP按字串長度分割成數組代碼_php執行個體

以下是我編寫的代碼，實現對中英文混雜字元進行分割：

<?phpfunction 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 = '我愛北京3我愛上海-我愛xianggang';$r = mbStrSplit($str, 4);echo '<pre>';print_r($r);echo '</pre>';?>

運行結果：

Array(  [0] => 我愛北京  [1] => 3我愛上  [2] => 海-我愛  [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);}?> $s ="還未如願sss見gfg者不rtret不朽"; // Mild milk print_r(str_split($s, 5)); print_r(str_split_unicode($s, 5));//輸出 //Array ( [0] => 還�� [1] => �如� [2] => ��sss [3] => 見gf [4] => g者� [5] => ��rtr [6] => et不 [7] => 朽 ) //Array ( [0] => 還未如願s [1] => ss見gf [2] => g者不rt [3] => ret不朽 )
