How to Resolve PHP Linefeeds (\n) Not Working issue

When you run a PHP script in a browser, it will be rendered as HTML by default. If the books you’re using show otherwise, then either the code or the illustration is inaccurate. You can use “view source” to view what was sent to the browser and you’ll see that your line feeds are present.

<?php
echo "Line 1\nLine 2";
?>

This will render in your browser as:

Line 1 Line 2

If you need to send plain text to your browser, you can use something like:

<?php
header('Content-type: text/plain');
echo "Line 1\nLine 2";
?>

This will output:

Line 1
Line 2
