The PHP that supports Chinese is divided into array codes according to the length of the string

The PHP written by myself is divided into array codes according to the length of the string and supports Chinese characters. The code and usage are given below For the method, friends in need can refer to it.

The following is the code I wrote to segment Chinese and English mixed characters:

　?

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> '; ?>

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 )

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 = 'I love Beijing 3 I love Shanghai-I love xianggang'; $r = mbStrSplit($str, 4); echo '

';
            print_r($r);
            echo '

'; ?>

Running results: 　?

1 2 3 4 5 6 7 8 9

Array ( [0] => I love Beijing [1] => 3 I’m in love [2] => Sea-I love [3] => xian [4] => ggan [5] => g )
