Would like to pass a value to another page without using <form></form>. Using this to "Email Page To Friend"

Rough Example - where $WebPage is

<?php
$scriptname = getenv("SCRIPT_NAME");
$httphost = getenv("HTTP_HOST");
$WebPage = "http://www." . $httphost . $scriptname;
?>

<a href="MailToPage.php?$WebPage">Mail This To Friend</a>
