hello,
can anyone help me decode this code and tell me step by step how to decode it:

Code:
<?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);    $TFF44570ACA8241914870AFBC310CDB85 = __FILE__;    $TFF44570ACA8241914870AFBC310CDB85 = file_get_contents($TFF44570ACA8241914870AFBC310CDB85);    $TA5F3C6A11B03839D46AF9FB43C97C188 = 0;    preg_match(base64_decode("LyhwcmludHxzcHJpbnR8ZWNobykv"), $TFF44570ACA8241914870AFBC310CDB85, $TA5F3C6A11B03839D46AF9FB43C97C188);    for (;$T3A3EA00CFC35332CEDF6E5E9A32E94DA<$TDD7536794B63BF90ECCFD37F9B147D7F;)    {     if (count($TA5F3C6A11B03839D46AF9FB43C97C188)) exit;     if ($TDFCF28D0734569A6A693BC8194DE62BF == 0)     {      $TF623E75AF30E62BBD73D6DF5B50BB7B5 = (ord($TF186217753C37B9B9F958D906208506E[$T3A3EA00CFC35332CEDF6E5E9A32E94DA++]) << 8);      $TF623E75AF30E62BBD73D6DF5B50BB7B5 += ord($TF186217753C37B9B9F958D906208506E[$T3A3EA00CFC35332CEDF6E5E9A32E94DA++]);      $TDFCF28D0734569A6A693BC8194DE62BF = 16;     }     if ($TF623E75AF30E62BBD73D6DF5B50BB7B5 & 0x8000)     {      $T7FC56270E7A70FA81A5935B72EACBE29 = (ord($TF186217753C37B9B9F958D906208506E[$T3A3EA00CFC35332CEDF6E5E9A32E94DA++]) << 4);      $T7FC56270E7A70FA81A5935B72EACBE29 += (ord($TF186217753C37B9B9F958D906208506E[$T3A3EA00CFC35332CEDF6E5E9A32E94DA]) >> 4);      if ($T7FC56270E7A70FA81A5935B72EACBE29)      {       $T9D5ED678FE57BCCA610140957AFAB571 = (ord($TF186217753C37B9B9F958D906208506E[$T3A3EA00CFC35332CEDF6E5E9A32E94DA++]) & 0x0F) + 3;       for ($T0D61F8370CAD1D412F80B84D143E1257 = 0;

It is Indonesian.
comment out the part:
if (count($TA5F3C6A11B03839D46AF9FB43C97C188)) exit;
otherwise it will not work.
Then copy it in a run.php file run it in linux box:
php run.php> injected.php
the result will be the exploit that expects GET parameters:
g,f,button,kelompok,checkbox,filter,desc,del

This is the decoded form. Also it is very confusing that the script 'echo's the PHP code instead of evaluating it.

Code:

<link href="../../style.css" rel="stylesheet" type="text/css" />

<?
$d = $_GET['d'];
$f = $_GET['f'];
$button = $_POST['button'];
$kelompok= $_POST['kelompok'];
$checkbox = $_POST['checkbox'];
$filter = $_GET['filter'];
$desc = $_GET['desc'];

$del = $_GET["del"];
if($del){
   $id_kelompok = $del;
    Del1(kelompok,id_kelompok,$id_kelompok);
   Del1(kelompok_kontak,id_kelompok,$id_kelompok);
   $sql = "delete from hp natural join kelompok_kontak where id_kelompok = '$id_kelompok' ";
   mysql_query($sql);
}



if($button=="CARI"){
     $nama = $_POST[nama];
     $q .=" and kelompok LIKE '%$kelompok%' ";
}

if($filter){
      if(!$desc){
            $desc = "desc";
            $tautx = "&desc=$desc";
      }else{
            $desc = "";
            $taut .= "&desc=1";
     }
     $q = "ORDER BY $filter $desc";
     $taut .= "&filter=$filter";

}

$tautan = "?d=$d&f=$f$taut";
$tautanx = "?d=$d&f=$f$tautx";

require("include_lib/paginacao.class.php");

$query2 = mysql_query("SELECT id_kelompok FROM kelompok where id_kelompok !='0' $q ");
$quantos = mysql_num_rows($query2);

include "paging.inc.php";
$sql="select id_kelompok,id_kategori_kelompok,kelompok from kelompok where id_kelompok!='0' $q LIMIT $inicio, $limite_de_resultados_por_pg ";
$data=mysql_query($sql);
