PHP：在字边界截断文本 [英] PHP: Truncate text at word boundaries

问题描述

有没有人具有Drupal用来转换下列字符串的确切名称：

你好，你好吗，还有更多的文字。

into

你好，怎么...

。即，用于在x字之后切断句子的功能，然后添加一个elipsis。或者，如果任何人有一个这样做的php代码段，那将是太好了！

解决方案

似乎是 truncate_utf8（） in unicode.inc 。

Does anybody have the exact name of the function Drupal uses to turn the following string:

"Hello, how are you. Some more text."

into

"Hello, how..."

I.e. The function that's used to cut off a sentence after x words, and then add an elipsis. Alternatively, if anybody has a php snippet that does this, that would be great too!

解决方案

It seems to be truncate_utf8() in unicode.inc.
