How to make mailto headers depending on the parameter?

Question

PHP

Now I send letters like this send.php

Is it possible to make the From address dependent on the last Referal_ID parameter?
For example, if Referal_ID = 2, then in headers we write From: [email protected],
and if Referal_ID = 3, then in headers we write From: [email protected]

Answer 1

It is possible, for example:

switch($Refereal_ID) {
    case 2:
        $email_from = '[email protected]';
        break;
    case 3:
        $email_from = '[email protected]';
        break;
    default:
        $email_from = '[email protected]';
        break;
}

// ...

$headers = "From: $email_from \r\n";

More or less like this.
