如何将PHP中的字符串截断到与一定数量字符最接近的单词？
提问于 2018-01-05 07:17:52
I have a code snippet written in PHP that pulls a block of text from a database and sends it out to a widget on a webpage. The original block of text can be a lengthy article or a short sentence or two; but for this widget I can't display more than, say, 200 characters. I could use substr() to chop off the text at 200 chars, but the result would be cutting off in the middle of words-- what I really want is to chop the text at the end of the last 字在200个字符之前。

通过使用wordwrap功能。可以将文本分成多行，
substr($string, 0, strpos(wordwrap($string, $your_desired_width), "\n"));

这将返回单词的前200个字符：
preg_replace('/\s+?(\S+)?$/', '', substr($string, 0, 201));页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
