possible to limit amount of words?

[Rifts]

Hey quick question on my homepage there is a featured content section, which is populated from my DB some of the posts are really long so I would like to limit the amount of text. how can I do this?  also is there a way to make sure if does not cut a word in half?

 

thanks

figured it out.. in case anyone else needs this

<?php

function limit_words($string, $word_limit)
{
    $words = explode(" ",$string);
    return implode(" ",array_splice($words,0,$word_limit));
}


# Example Usage

$content = "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.";

echo limit_words($content,20);


?>
