Here is one that I had thrown together a while back:

function word_wrap($chars,$str){
~ $cpy=strip_tags($str);
~ $chk=array_reverse(preg_split('`\s`',$cpy));
~ $chk2=array_reverse(preg_split('`\s`',$str));
~ $len=0;
~ $retVal='';

~ // we want to work backwards on this
~ for($i=count($chk)-1;$i>=0;$i--){
~ // $len is the current segment length in the stripped string
~ if($len>0 && ($len + strlen($chk[$i])) > $chars){
~ // add a line break
~ $retVal.='<br />'."\n";
~ $len=0;
~ }else if($len>0){
~ // space between words needs to be counted
~ $len++;
~ }

~ // add the necessary pieces to the string
~ $pop1=array_pop($chk); // get next piece from each version
~ $pop2=array_pop($chk2);
~ $retVal.=$pop2.' ';
~ $len+=strlen($pop1);
~ $pattern='`'.preg_quote($pop1).'`';
~ while(!preg_match($pattern,strip_tags($pop2))){
~ // if pop1 and pop2 are not referencing the same element
~ $pop2=array_pop($chk2);
~ $retVal.=$pop2.' ';
~ if($pop2==NULL) break;
~ }
~ }
~ return $retVal;
}

It wraps plain text or HTML as it displays (doesn't count the HTML tags
when processing). The string is split on whitespace, if there is a piece
that is longer than the wrap, it outputs just that as it was input.
