自己编写的PHP按字符串长度分割成数组代码,支持中文字符,下面给出代码和使用方法,有需要的小伙伴可以参考下。
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 )
以上所述就是本文的全部内容了,希望大家能够喜欢。
