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

<?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：
|
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
)

<?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 )
