Answer 2

just universal solution (but maybe denied by local PHP-server configuration):

echo file('http://your-remote-host/path/a.php');

or your a.php must provide some gate:

<? # a.php
function a_php_output()
{
return "i'm a.php";
}
?>

<? # b.php
echo "i'm b.php";
include('a.php');
echo a_php_output();
?>
