I'm already familiar with the_excerpt() and get_the_excerpt() functions. These two functions relate specifically to some node/taxonomy/whatever (post, page, custom post type) inside of Wordpress, unless I'm mistaken.
What if I have some external text, and wanted to pass it through a concatenation function. Does anyone know the function to do that?
What I'm trying to avoid, is creating a new function or re-writing an old function to limit words inside of a string. For example,
echo some_excerpt_function($text, $amount_of_words_to_limit);
I'm assuming Wordpress has something similar to this, that's why I'm asking.
