PHP preg_split 为新行添加拆分

Question

我正在使用这个 preg_split 来拆分一个字符，只要有点后有 space 或大写字母字符：

$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，我现在还需要它来拆分新行（或行）。我无法理解它...:(

Answer 1

试试这个：

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

Answer 2

您可以使用匹配点后跟 0+ 个水平空白字符然后 1+ 个大写字符或 | unicode 换行符序列的交替来拆分：

\.(?=\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);
