为什么用多字节标点符号分割时会出现额外的空行？

Question

试试这个：

$pattern = '/[\x{ff0c},]/u';

//$string = "something here ; and there, oh,that's all!";
$string = 'hei,nihao，a ';


echo '<pre>', print_r( preg_split( $pattern, $string ), 1 ), '</pre>';
exit();

输出：

<pre>Array
(
    [0] => hei,nihao，a
)
</pre>

Answer 1

您拥有的字符是全角逗号（十六进制 ff0c ）以及常规逗号。您是否尝试过将其更新到我的版本？

<?php
$pattern = '/[\x{ff0c},]/u';

//$string = "something here ; and there, oh,that's all!";
$string = 'hei,nihao，a ';


echo '<pre>', print_r( preg_split( $pattern, $string ), 1 ), '</pre>';

输出：

Array
(
    [0] => hei
    [1] => nihao
    [2] => a 
)
