Print newline in PHP in single quotes
Difference between single quote and double quote string in php

$unit1 = 'paragrahp1';
$unit2 = 'paragrahp2';
echo '<p>' . $unit1 . '</p>\n';
echo '<p>' . $unit2 . '</p>';

This is displaying (on view source):

<p>paragraph1</p>\n<p>paragraph2</p>

but isnt what I’m expecting, not printing the new line, what can be?

Answer 1

PHP only interprets escaped characters (with the exception of the escaped backslash \\ and the escaped single quote \') when in double quotes (")

This works (results in a newline):

"\n"

This does not result in a newline:

'\n'
