Sample PHP code

wolf@linux:~$ cat 1-new-line.php 
<?php
echo "Hello
World
Foo Bar!";

$aString = '
First Line
Second Line
Third Line';
echo $aString;
?>

wolf@linux:~$

It runs as expected in CLI

wolf@linux:~$ php 1-new-line.php 
Hello
World
Foo Bar!
First Line
Second Line
Third Line
wolf@linux:~$

But not via browser

What's wrong in this code? How to render it properly in web browser?

Browsers interpret PHP's output as HTML, and in HTML newlines get replaced by spaces.

If you want to learn how to line-break in a browser, use <br /> or wrap sentences in <p> tags.

You can also tell a browser to treat your output as text, and not HTML. In that case, use the following header (before any output):

header('Content-Type: text/plain');

  • Thanks @Evert. Can you show the right way to use `header('Content-Type: text/plain');`. I've tried it but did not get the output that I wanted. –  Nov 01 '20 at 07:15
  • The way I wrote it is the way you use it. It must appear before any other output. If that doesn't work, share more information. – Evert Nov 01 '20 at 07:19

You are rendering it in a browser without any HTML formatting. Wrapping it in a <pre></pre> tags will preserve its plaintext formatting (newlines and whitespace) when rendered in the browser.

<pre>
<?php
echo "Hello
World
Foo Bar!";
</pre>


$aString = '
First Line
Second Line
Third Line';

<pre>
echo $aString;
</pre>
?>
