这个 PHP 是如何编码的?

Does anybody know how this PHP code is encoded? I don't know whether it's Zend, ionCube or something else.

<?php

if (!function_exists("T7FC56270E7A70FA81A5935B72EACBE29"))  {
    function T7FC56270E7A70FA81A5935B72EACBE29($TF186217753C37B9B9F958D906208506E)   { 
        $TF186217753C37B9B9F958D906208506E = base64_decode($TF186217753C37B9B9F958D906208506E);
        $T7FC56270E7A70FA81A5935B72EACBE29 = 0;
        $T9D5ED678FE57BCCA610140957AFAB571 = 0;
        $T0D61F8370CAD1D412F80B84D143E1257 = 0;
        $TF623E75AF30E62BBD73D6DF5B50BB7B5 = (ord($TF186217753C37B9B9F958D906208506E[1]) << 8) + ord($TF186217753C37B9B9F958D906208506E[2]);
        $T3A3EA00CFC35332CEDF6E5E9A32E94DA = 3;
        $T800618943025315F869E4E1F09471012 = 0; 
        $TDFCF28D0734569A6A693BC8194DE62BF = 16;
        $TC1D9F50F86825A1A2302EC2449C17196 = "";
        $TDD7536794B63BF90ECCFD37F9B147D7F = strlen($TF186217753C37B9B9F958D906208506E);
?>

这只是混淆代码.我猜它是由 http://www.truebug.com/ 生成的，根据 这个缓存的 Google 页面，但它可以来自任何类似的产品.
