PHP Linefeeds (\n) Not Working

Closed 6 years ago.
The code is in double quotes and still not working.
I already read this post
I'm using Atom and am on localhost (if that makes any difference)
I redownloaded Atom (in case there was something going on with the settings) and that didn't help
Here's the code:
<?php
$firstName = 'David';
$lastName = "Powers";
$title = '"The Hitchhiker\'s Guide to the Galaxy"';
$author = 'Douglas Adams';
$answer = 42;
$newLines = "\r\n\r\n";
$fullName = "$firstName $lastName |";
$book = "$title by $author";
$message = "Name: $fullName $newLines";
$message .= "Book: $book \r\n\r\n";
$message .= "Answer: $answer";
echo $message;
echo "Line 1\nLine 2";
Output is all one line, but when I view source the new lines are working
Name: David Powers | Book: "The Hitchhiker's Guide to the Galaxy" by Douglas Adams Answer: 42Line 1 Line 2

Answer 1

This is the first thing you will learn if you are learning even from a PHP 5 For Dummies book. HTML doesn't respect new line or tab or multiple space characters. You have to use <br /> for new lines.
* Sourced from PHP 5 For Dummies by Janet Valade.
Change your code to:
<?php
$firstName = 'David';
$lastName = "Powers";
$title = '"The Hitchhiker\'s Guide to the Galaxy"';
$author = 'Douglas Adams';
$answer = 42;
$newLines = "<br /><br />";
$fullName = "$firstName $lastName |";
$book = "$title by $author";
$message = "Name: $fullName $newLines";
$message .= "Book: $book <br /><br />";
$message .= "Answer: $answer";
echo $message;
echo "Line 1<br />Line 2";
If you are just opting for a text based layout, you can set the header to the browser to respect it as just a text file. For that, you need:
header("Content-type: text/plain");
This will render without any HTML.

Answer 2

By default, when a PHP script is run, the content type of the result is set to text/html. When browsers render HTML, newlines are not normally respected, they're treated like any other whitespace.
If you want all your output formatting to stay the same, and you're not sending HTML, tell the browser that you're sending plain text. Put this at the beginning of the code:
header("Content-type: text/plain");

Answer 3

As well Praveen Kumar mention how to print new lines in echo.
But if you still want to use escape sequences then use print_f You can use other escape sequences like \t,\n in printf.
<?php
$firstName = 'David';
$lastName = "Powers";
$title = '"The Hitchhiker\'s Guide to the Galaxy"';
$author = 'Douglas Adams';
$answer = 42;
$newLines = "\r\n\r\n";
$fullName = "$firstName $lastName |";
$book = "$title by $author";
$message = "Name: $fullName $newLines";
$message .= "Book: $book \r\n\r\n";
$message .= "Answer: $answer";
printf ($message);
printf ("Line 1\nLine 2");
