How to indent to not affect formatting of plain text emails?

PHP
1 
if ($guideMemberNumber) {

$extraMessage = "Don't forget to login with your member number.";}

When I indent the above code on my php age, it also indents the text when I send a simple email. Is there a way I can indent my code to keep things organized and NOT have it affect an email that is sent?

Thanks!

You can use single quotes and it won’t format it. But it also means you have to manually put in the line breaks/tabs.
