Creating a snippet or excerpt of words from a text body in PHP

This is a little helpful function I wrote in PHP to make a content snippet that tries to prevent cutting off halfway through a word.  It keeps the number of words to a given amount and also restricts the text to a specfic length if the words go over the character limit. It is pretty simple but works great!

function excerpt($text, $words=12, $end='...',$limit=120) {
    // split the string by spaces into an array
    $split = explode(' ',$text);


    if (count($split)>$words) {
        // rebuild the excerpt back into a string
        $text = join(' ',array_slice($split,0,$words));
    }


    // append the ending, limit it, and return
    return substr($text,0,$limit-length($end)).$end;
}

There you go, happy coding!
