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[0]) + 1;
It'll always output 1.
Is there any other solutions to count lines in a string?

$filePath = "test. txt" ; $lines = count (file( $filePath ));
Use readlines() to get Line Count This is the most straightforward way to count the number of lines in a text file in Python. The readlines() method reads all lines from a file and stores it in a list. Next, use the len() function to find the length of the list which is nothing but total lines present in a file.
Check out the function getClientRects() which can be used to count the number of lines in an element.
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/>
