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);
}
This works well, except it is also removing any line breaks. For
instance...

I'd like to (need to) retain the line breaks. Any suggestions?
Thanks,
