Copas Code ini :

#!/usr/bin/php
/*
* this script find some shell like
* c99, c100, r57, erne, Safe_Over
* and try to find some of unknow shell searching specific words this can be
* not safe
*
* how to use:
* the script don't need no-one of these parameter thay are facoltative
* -e Y/N enable disable eusristic mode (default is enable)
* -p a number 1-100 , it's the percentual of word that must be find into the file to warm the euristic mode
* -f check a single file
* -d check a single dir (normaly the program is recursive chek ALL file )

Lalu, simpan dengan nama amankan.php ato serah ente dah
panggil url nah ... http://situslo/amankan.php
ntar tinggal liat hasilnah....
