Description:
------------
It is possible to post data to an script on an external server. I find this a huge bug in the php api, because of this harmfull persons can add/alter any kind of data to a script. Will this be resolved in a future PHP version?

Reproduce code:
---------------
[external server]
<?php
ini_set("register_globals", 1);

$variabel = $_POST["test_var"];

if(!empty($variabel)){
	print "This is the bug I'm talking about";
}
?>

[other server]
<form method="post" action="http://my.external.site/externalphpscript.php">
<input type="text" name="test_var">
<input type="submit" value="Test">
</form>

Expected result:
----------------
This is the bug I'm talking about
