在php中用句號分隔字符串排除「a.m.」

Question

我在PHP中使用preg_split函數將段落拆分爲幾個句子。

在我的情況：

$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); 

，如何排除的情況下，當有一個a.m.或p.m.？

Answer 1

您應該可以使用(*SKIP)(*FAIL)來阻止am/pm匹配。您可以在這裏閱讀更多關於此方法的信息，http://www.rexegg.com/regex-best-trick.html。

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); 

輸出：

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A.M.也應該被允許使用imodifier。
