PHP:在单词边界处截断文本
有人知道 Drupal 用来转换以下字符串的函数的确切名称吗:
Does anybody have the exact name of the function Drupal uses to turn the following string:
你好，你好吗.还有一些文字."
"Hello, how are you. Some more text."
进入
你好，怎么..."
即用于在x个单词后截断一个句子，然后添加省略号的函数.或者，如果有人有执行此操作的 php 代码段，那也太棒了！
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!
推荐答案
unicode.inc中好像是truncate_utf8().
