PHP preg_split为新行添加拆分

Question

我使用这个preg_split来分割一个pharagraph，只要后面有空格或大写字母字符的点：

$p = "This is a dummy text. And it has a new line in it n it also has dots. Byt not";
$arr  = preg_split('/.s*?(?=[A-Z])/', $p);

这也防止了段落中的最后一个点被拆分(这是我想要的(，但是，我现在也需要它来拆分新行(或行(。我无法用我的头脑去理解它…：(

Answer 1

试试这个：

$arr  = preg_split('/.s*?(?=[A-Z])|(rn|n|r)/', $p);

Answer 2

您可以使用一个替换来进行拆分，该替换匹配一个点，后跟0+水平空白字符，然后是1+大写字符，或者|一个unicode换行序列：

.(?=h*[A-Z])|R+

例如：

$p = "This is a dummy text. And it has a new line in it n it also has dots. Byt not.";
$arr  = preg_split('/.(?=h*[A-Z])|R+/', $p);
