Do You Guys Know About Nul Byte Characters? Help :d

[everluck]

I have a script written in php (attached below), the content was accidentaly became unreadable, and if I open it with Notepad++, it shows NUL NUL NUL NUL (text color: white, background color: black).

 

It happened because I did force shut down while the script proccessing and my laptop freeze up.

 

Is it true that the file turned into binary file (nul byte)? How could it be? And the most important for now, how do I restore it to string file or readable again?

sorry for my bad english, thanks for your help

Every file is a binary file as they are made out of 1s and 0s.

I don't think it is possible to restore it as it is filled with 0s and there is no way to tell what has been there.

yep sorry my mistake, newbie here hehe

yah I think so, nul means nul, null means null

thanks man

NULL == NUL == \0, just different ways of writing it depending upon the context.

yes, i mean empty is empty, if it is nul, so it is nul, it can not be restored because it is already empty
