PHP and Qmail

[AlphaZ]

I have been trying to have Qmail pipe emails to a script from a certain address. I had it successfully send it over to another email, so I know it is recieving and proccessing the email. However, when I try:
|/path/to/script.php
it doesnt do anything, not even bounce back. I cant find the qmail logs either. So, Im screwed. I googled for about a day, and I am stuck. I tried to execute /path/to/script.php in the shell, and I get:

I know I have php installed, I can execute php /path/to/script.php just fine.

Here is my simple code (for debugging, really)

#!/usr/bin/php
<?
// read from stdin
mail("[e-mail]","Recieved!","Recieved email!");
$fd = fopen("php://stdin", "r");
$email = "";
while (!feof($fd)) {
    $email .= fread($fd, 1024);
}
fclose($fd);
mail("[e-mail]","Proccessed Email",$email);
?>

In my .qmail-thepipe file, I even tried to pipe using these:
|php -f /path/to/script.php
|php -q /path/to/script.php.
|php /path/to/script.php
|/path/to/script.php

None, works.

Thanks for your help!
