[RESOLVED] Multiple Headers in Form mail

[Rivet]

Win 7, XAMPP local, PHP 5.3.
I came across this quite by accident for using multiple Headers in a mailto() form I was having trouble getting to work the way I wanted it to. Namely:

$to = "some address";
$subject = "Some Form\n";
$header = "From: $name\n";
$header .= "Reply-To: address\n";
$header .= "Return-Path: address\n";

I'm specifically referring to the " .= " in the 2nd & 3rd $header lines. It makes sense I think and it's able to be called as simply $Header in the mailto() line.

Now I'm trying to apply something similar to other fields I'd like delivered to me when I receive the visitor's email form. The " .= " is apparently only good for Headers??
I've tried to Google, looked at php.net and w3schools, but cannot find either the " .= " or any other method of putting things together to send additional data to me when I received the forms. For instance, I'd like to combine the Message, the Sender's name and his e-mail address into one collection similar to what I did with the Headers. My mailto line looks like:

if(mail($to,$subject, $comments, $respond, $header)) { ...

I'd appreciate 1. any leads, URLs or even sample code on how to go about this, and also 2. Any links that talk about the " .= " business, too.

TIA.

It's explained on the manual page for assignment operators: [man]operators.assignment[/man]. Simply put, this:

$a = $b;
$a .= $c;

is the same as writing:

$a = $b;
$a = $a . $c;

or even just:

$a = $b . $c;

Thus, no, that language construct has no special influence on only the 'additional_headers' parameter for the mail() function.

THANKS! That explains a lot!
