I've tried this: count new lines in textarea to resize container in PHP?
But it doesn't seems to be working:
$content = nl2br($_POST['text']);
preg_match_all("/(<br>)/", $content, $matches);
echo count($matches) + 1;
Found this in one of my old apps... Not sure where I got it from.
$lines_arr = preg_split('/\n|\r/',$str); $num_newlines = count($lines_arr); echo $num_newlines;
*Edit - Actually, this probably won't work if your textarea is spitting out html.. check for
<br> and <br/>
