php - 被各种分隔符分割，同时保留分隔符？

Answer 1

Try this:

$lines = preg_split('/(?<=[。！？])(?![。！？])/u',$body);

It splits at a position that's preceded by one of your delimiter characters but not followed by one. It doesn't consume the delimiter, and if there are two or more consecutive delimiters, it only matches after the last one.

Answer 2

In this case, you'd like to write the string splitter yourself. And keep continuous delimiters as a whole. (you can set a state variable indicating whether it is in text block or delimiter block).

Answer 3

You should use preg_match_all instead of preg_split, i.e.

preg_match_all("/[^？！。]+[？！。]+/u", $text, $res);
