Paragraphs in textarea

Question

I have a form that has a textarea in it. How would I make new lines in the textarea appear as new paragraphs when I echo out the submitted textarea value?

Answer 1

<?php
    $textarea = $_POST['textarea'];

    $newarr = explode("\n", $textarea);

    foreach($newarr as $str) {

        echo "<p>".$str."</p>";

    }
?>
