Need some PHP help

[A.J. Angel]

Hey there,

I need some help from someone who is good in PHP. Currently, I am using the following code to hide my affiliate links:

<?php

$path = array(

"amateursgonebad" => "http://www.amateursgonebad.com/t1/revs=exquisiteangelz/",
"glamourmodelsgonebad" => "http://www.glamourmodelsgonebad.com/t1/revs=exquisiteangelz/"

);

if (array_key_exists($_GET["id"], $path))
header("location: " . $path[$_GET["id"]]);

?>

Now, considering that the files which contains the code is called "index.php" and that it is located in a subdirectory called "redirect", how may I redirect surfers that go to the file in question directly (ie. "http://www.domain.com/redirect/index.php") be redirected back to my homepage while still being able to use the code above to hide my affiliate links? Any ideas or indications would greatly appreciated. Thanks!

header("location: " . $path[$_GET["id"]]);
} else {
header("location: http://yoursite.com/");
}
