Ah, okay. I tried all the substr() calls and they appear to work properly.
However, the second substr() call is taking the last six characters off
the end of the string "$host", and not the first six characters as I
imagine you are trying to do.

Here's some sample code I put together to test this:

<?php
$host = 'a1b2c3d4e5f6';
$sub = substr($host, 6);
print "$sub\n";
?>

The above code results in the string "d4e5f6" being printed out, and not
"a1b2c3" as you may expect. If you want only the first six characters,
set the second parameter to 0 (zero) and the third parameter to 6.
