PHP5 - Php code to get password

hello gays ,
I have a file with the an encrypted password , and I need some php code who to get this password from this file with encrypted password , i try to do AutoID

Are you talking about some kind of magic function which decrypts any file automagically?

No, no, not what I meant. I have a web chat, and I want to do spoof host. So I need this code to make the encrypted password can enter a host.

Yeah... That doesn't help me in the slightest bit. Still have no idea what you're talking about, except there's a file and apparently it contains an encrypted password.
Try describing your situation and how this file/password has anything to do with it.

are you talking about spoofing as an attack? or do you just want to read the file?
If so than use for instance fread (cannot post the url, but you find the function on php.net)
