Trim headline to nearest word

Question

Say for example I have the following code:

My very long title
Another long title

If I wanted to

Answer 1

using some php and the mighty regular expressions

function formatHeadline($headline){
    if(preg_match('/(\w+\s+){3}/', $subject, $match)){
        return $match[1]  . '...';
    }
    return $headline;
}

The same method should be possible in javascript using regex and jquery.

Jquery also have the ellipsis plugin, you might want to look into it.
