How about substr?

/* Using regular expression */

$firstTwenty = trim(preg_replace('/^\s*((?:\S+\s+){20}).*/', '$1', $inputText));

/* Using split and combine */

$firstTwenty = implode(' ', array_slice(explode(' ', $inputText), 0, 20));

I can't remember where and if it is even true at all, but it seems to me I saw some helper functions in PW to do exactly that - summaries limited by words + ellipsis. Does anyone know what I am talking about?

Ryan gave an example of how to do this in a blog post recently.
