textarea中的段落

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>";

    }
?>

Answer 2

Use nl2br function:

<?php 

echo nl2br($_POST['textarea']);

?>

It will print <br> all newlines

Answer 3

echo '<p>' . preg_replace("~[\r\n]+~", '</p><p>', $textarea) . '</p>';
