I am trying to assign a variable to email body in php but is not working.

$refer=$_POST['refer'];
send_mail(  'admin@auto-sal.es',
                    $_POST['email'],
                    'Invitation from ' .$name,
                    'Hi ".$refer."\n\n join me at auto-sal.es and get 1 month free membership');

    Try this:

    "Hi \"$refer\"\n\n join me at auto-sal.es and get 1 month free membership");

    You are enclosing the string in single quotes. Single quotes work differently from dobule quotes. If you put " or a variable inside single quotes they will be interpreted literally, and that’s what is happening to you.

    You should also take a look at the official documentation that states:

    Unlike the double-quoted and heredoc syntaxes, variables and escape sequences for special characters will not be expanded when they occur in single quoted strings.
