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:
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |
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 ' '; <p>print_r($r);</p> <p>echo '</p>'; ?> |
运行结果:
?
1 2 3 4 5 6 7 8 9 |
Array ( [0] => 我爱北京 [1] => 3我爱上 [2] => 海-我爱 [3] => xian [4] => ggan [5] => g ) |
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 |
function str_split_unicode($str, $l = 0) { if ($l > 0) { $ret = array(); $len = mb_strlen($str,"UTF-8"); for ($i = 0; $i $ret[] = mb_substr($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 ) |
