How to put a break in an email variable?

Question

So I'm working on a mail form for my site and I got i working. Now I want to personalise it with a cutsom message but... I have no idea how to put line breaks in the variable message. I tried using <br />but that just prints it out as a word. So any idea's?

P.S. I may be totally wrong feel free to totally change what is in the message I just want to understand the concept.

<?php
$message =
"You recieved mail from  $mail with a question." . 
"The question contains the following:" . 
"$_POST['message'];";
?>

EDIT: @Ben Pearl Kahan answer worked for me! Thanks for the answers!

Answer 1

In double quotes, \r\n will be a new line.

Example:

<?php
    $message =
    "You recieved mail from  $mail with a question.\r\n" . 
    "The question contains the following:\r\n" . 
    $_POST['message'];
?>

FYI, "$_POST['message']" is not correct concatenation; you should either process the array variable outside the string:

"text ".$_POST["message"]." more text"

or use curly brackets (NB: this will only work if your string is enclosed in double quotes):

"text {$_POST["message"]} more text"
