我是 PHP 的新手。我有一个像这样的字符串:

$string="Once the Flash message has been set, I redirect the user to the form or a list of results. That is needed in order to get the flash working (you cannot just load the view in this case… well, you can but this method will not work in such case). When comparing $result TRUE or FALSE, please notice the different value for type. I am using type=message for successful messages, and type=error for error mesages.";

现在我只想显示 15 或 20 之类的有限单词。我该怎么做呢?
