1,3 - same as REMOTE_ADDR and HTTP_REFERER is nothing specific for php
2. $uself is a variable and that line means if $uself exists or is equal to 0 the variable $headersep is "\r\n" else is "\n".

You will benefit from searching the manual, available at http://php.net.

The $_SESSION superglobal is explained here:

To add to Fumigator's post I think you were looking for the mail() function.
