Hi Richard,
I quickly realized this and fooled with a few variations. Also have to
take into account that the <br> or the <br /> get counted as 1 or 2
words respectively, and so the trim can end up in the wrong place. I've
tried fiddling with counting the number of br's in the string and
adding that to the truncation limit before the preg_split, but this is
still not ideal.
I'm going to have a look at your other suggestion too.
Thanks for your thoughts :)

This would work if you replace the <br /> with <br> -- Otherwise, it's
too likely to break up "<br />" in the trim_text function and then you
end up with:
"start of string ... almost 255 words, blah blah blah<br"

Hi :)
I am using the following function (that I found in the user comments
on
php.net manual) for trimming the number of words accepted via a form
field
// Truncation is by word limit, not character limit. So if you limit
// to 255, then it will cut off a text item to 255 words, not 255
characters
function trim_text ($string, $truncation=250) {
$string = preg_split("/\s+/",$string,($truncation+1));
unset($string[(sizeof($string)-1)]);
return implode(' ',$string);
}
How about
$string = nl2br($string);
$string = trim_text($string);
$string = str_replace("<br />","\n",$string);
