File Formats
All scripts contributed to PEAR must:
-
Be stored as ASCII text
-
Use ISO-8859-1 or UTF-8 character encoding. The encoding may be
declared using declare(encoding = 'utf-8'); at the
top of the file.
-
Be Unix formatted
"Unix formatted" means two things:
1) Lines must end only with a line feed (LF).
Line feeds are represented as
ordinal 10,
octal 012 and
hex 0A.
Do not use carriage returns (CR)
like Macintosh computers do
or the carriage return/line feed combination
(CRLF) like Windows computers do.
2) There should be one line feed
after the closing PHP tag (?>).
This means that when the cursor is at the very end
of the file, it should be one
line below the closing PHP tag.

| User Notes: |
I don't like these rules.
You require @author tag, and my name cannot be properly written in ASCII or ISO-8859-1. I think requirement of UTF-8 is much more reasonable these days.
Although "?>\n" is harmless, any accidentally added lines after that will be output and will cause trouble. I don't see any benefit in having "?>" and I see potential pitfalls, so IMHO it should be forbidden, rather than required.
shiplu.net..., you're wrong. The described line feeds are intended to not cause trouble e.g. with the header() or with session functions. Problems would arise only if there would be any more whitespace after the closing tag.
Note by: shiplu.net@gmail.com
LF after ?> is not a good idea.
It'll cause problem while working with headers.
I think this rule should be omitted.
cbrunet: Adding a single line-feed after the closing ?> does not cause headers to be sent. It is ignored by PHP.
Adding a LF after the last ?> could cause a problem to scripts that need to be executed before headers are sent. I will send a newline to the browser, causing headers to be send.

Whay not use the unicode utf-8 format?
