有没有人有一个PHP代码段来抓取第一个“句子”？一串？ [英] Does anyone have a PHP snippet of code for grabbing the first "sentence" in a string?

问题描述

如果我有这样的描述：

我们更喜欢可以回答的问题，而不仅仅是讨论的问题。请提供详细信息。请写清楚而且简单。

"We prefer questions that can be answered, not just discussed. Provide details. Write clearly and simply."

我想要的就是：

我们更喜欢可以回答的问题，而不仅仅是讨论的问题。

"We prefer questions that can be answered, not just discussed."

我想我会搜索常规的表达式，例如 [。！\？]，确定strpos，然后在主字符串中执行substr，但是我想这是很平常的事情，所以希望有人在附近放一个片段。

I figure I would search for a regular expression, like "[.!\?]", determine the strpos and then do a substr from the main string, but I imagine it's a common thing to do, so hoping someone has a snippet lying around.

推荐答案

稍微昂贵一点的表达式，但是，如果您希望选择多种类型的标点符号作为句子终止符，则该表达式将更具适应性。

A slightly more costly expression, however will be more adaptable if you wish to select multiple types of punctuation as sentence terminators.

$sentence = preg_replace('/([^?!.]*.).*/', '\\1', $string);

查找终止字符后跟空格

$sentence = preg_replace('/(.*?[?!.](?=\s|$)).*/', '\\1', $string);
