When I edit the php file using notepad all indent is lost using NuSphere Editor. I see there are 3-10 banks lines between each lines of code.

I want to code to be indented removing these blank line. How I can ident it to it original format?

Blank lines added between lines of code?
Indenting only applies horizontally (ie tabs vs spaces and the amount of it).
Unless the line ending format is different between PhpED and notepad I cant think of anything that would cause it.
Can you post a screenshot of the file seen in notepad and in phped?

blank lines are often inserted by loosy ftp servers that replace \n\r (windows line endings) with \n\n. It has nothing to do with PhpED or it's ftp client.
There are three possible solutions: 1) upgrade FTP server that won't replace \r with \n 2) use binary mode for all FTP file transfers 3) use only linux/unix line endings (\n).
