Syntax for text formatting

This is the php that is used in Form2Mail.


$message .= "$var:$val
";

If I wanted to make the $var in bold text what would be the correct syntax? I tried this:


$message .= "<b>$var:</b>$val
";

But the message ending up being <b>name:</b>=name in the email!

Also if you have multiple lines in $val, e.g if it was an address - is there a way to format it so that the second line starts under the first as if it were tabbed?

rather than

Address: First Line
Second Line
Third Line

Any help greatly appreciated thanks. :be:
