在 php 中用句号拆分字符串排除"a.m."

Question

我使用PHP中的preg_split函数将一段拆分为多个句子。

就我而言：

$str = 'Applicants can check the final result of Admissions through the online enquiry system. The online enquiry system will be available from 10:00 a.m. on November 16 (Wednesday).';
$arr = preg_split('/./', $str);

当存在a.m.或p.m.时，我如何排除这种情况？

您应该能够使用(*SKIP)(*FAIL)来阻止am/pm匹配。你可以在这里阅读更多关于这种方法的信息，http://www.rexegg.com/regex-best-trick.html.

[ap].m.(*SKIP)(*FAIL)|.

PHP用法：

$str = 'Applicants can check the final result of Admissions through the online enquiry system. The online enquiry system will be available from 10:00 a.m. on November 16 (Wednesday).';
$arr = preg_split('/[ap].m.(*SKIP)(*FAIL)|./', $str);
print_r($arr);

输出：

Array
(
    [0] => Applicants can check the final result of Admissions through the online enquiry system
    [1] =>  The online enquiry system will be available from 10:00 a.m. on November 16 (Wednesday)
    [2] => 
)

如果还应允许使用A.M.，请使用i修饰符。
