count new lines in textarea to resize container in PHP?

Question

I have a textarea submitted to a php file.

Im using this to make it look exactly as the user entered the text:

 $ad_text=nl2br(wordwrap($_POST['annonsera_text'], 47, "\n", true));

If I want to resize a container I must be able to read how many lines are in the variable '$ad_text'.

Is there a way to do this...

I am still learning so thanks for your help...

Answer 1

$lines = explode($text, "\n");
$count = count($lines);
$html = implode($lines, "<br>");

Answer 2

You want the substr_count function.
