I am not sure if this is an Ubuntu, Apache or PHP issue.
The following basic scripts do not render a new line in my Firefox browser.
echo "this is not \n creating a new line";echo "this is not \r\n creating a new line";echo "this is not creating a new line";
I am currently learning PHP and have no idea where to even start solving this. All I know from Googling is that the above 3 should work.
This works
echo "this does <br> create a new line";
My setup:
Ubuntu 18.04.2
Apache/ 2.4.29 (ubuntu)
PHP 7.3.7-2+ubuntu18.04.1

Snooping bit further I found that the <pre> tag also works when combined with \n. Why is that?
<html> <body> <h1>Some h1</h1> <p>Some text</p> <pre> <?php echo "this is not \n creating a new line";?> </pre> </body>
</html>2 Answers
A new line inside the html source code is not displayed as a newline in a browser.
Take a look at the source code of your generated html pages, you will find your newlines
The html code of a new line is <br>
In short
<?php echo "\r\n"; ?> // Writes a new line in the output stream
<?php echo "<br>"; ?> // Writes the newline html codeAnother example:
<php
echo "<html><body>A<br>\r\nB<br>C\r\n</body></html>"
?>Will output the raw text:
<html><body>A<br>
B<br>C
</body></html>A browser will display this
A
B
CAFAIK, lines break are made with <br> or <br /> tags.
You can convert \n to <br /> with nl2br function:
<?php $line = "First line\nSecond line." echo nl2br($line);
?>
