PHP preg_split 为新行添加拆分

Question

我使用这个preg_split 来分割一个短语，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);

这也可以防止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）。我无法设法绕开它...... :(

Answer 1

试试这个：

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

Answer 2

您可以使用与点后跟 0+ 个水平空白字符，然后是 1+ 个大写字符或 | Unicode 换行符序列相匹配的交替进行拆分：

\.(?=\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);
