php and stdin

Helo guys and girls.

Before I explain my problem, this envolves a bit of *nix too, but has more
effect on php than *nix, so I hope you guys understand, I doubt asking this
question in a *nix group will result in any answers :-)

Here is my problem:
I wanna read something from stdin, and then write it to a file.
Now that part is not so hectic, the trick is, I wanna use it from syslogd.

My script that reads stdin (which I will show the code of a bit later) works
fine if I use it like this:
echo "testing123" | /usr/local/bin/php update.php
The script takes the text "testing123" and then writes it a file I specify.

If I use it in syslog.conf using the following (2) method(s), it does
nothing:
security.* |/usr/local/bin/php /path/to-the-script/update.php
security.* |exec /usr/local/bin/php /path/to-the-script/update.php

This is on a FreeBSD 5.3 machine.
What I want to do, is read the logging of ipfw, and then write it to mysql,
but before I start writing it to mysql, I first
wanna try and just write it to a normal file, from stdin, but when ever ipfw
logs something, it doesn't seem as though my script
gets excecuted as well.

Here is the code I have for update.php script:

<?php

$tmpfile = 'flogger.tmp';
$stdin = fopen('php://stdin','r');

while(!feof($stdin)) {
$mybuffer = fread($stdin, 2048);
$thetmpfile = fopen($tmpfile, 'a');
fwrite($thetmpfile, $mybuffer);
fclose($thetmpfile);
}
fclose($stdin);

?>

Now since it works from command line, I might be doing something wrong with
my syslog.conf, but I am not sure.

Would really appreaciate it if someone can point me in the right direction.

Thanks in advance.

I'm largely guessing here, but:

1) did you remembr to restart / HUP the syslogd?
2) syslog may be splitting the argument - try enclosing it in quotes or
making update.php executable and omit the '/usr/local/bin/php' bit
3) make sure your syslogd isn't running chroot

I tried adding #!/usr/local/bin/php at the top of the file, and also making
it excecutable, but to no avail :-/

Someone must have wanted to do something similar previously, or know where I
am going wrong.
