#1: PHP EOL

Hello All,
Happy pre independence for my American PHPers. And good health to all
others.
Have a quick question..

I have this code I use for the end of line characters used in my
mailers.

[Code]
// Is the OS Windows or Mac or Linux
if (strtoupper(substr(PHP_OS,0,5)=='WIN')) {
$eol="\r\n";
} else if (strtoupper(substr(PHP_OS,0,5)=='MAC')) {
$eol="\r";
} else {
$eol="\n";
}
[End Code]

Does this suffice or should I be using the php supplied end of line?

$eol=PHP_EOL;

Or do these do the same thing?
What advantages over the code I use does the PHP_EOL have?
Or does it not matter with these and either are good to go?

It seems to me that they do the same thing.. am I on the right track
or missing something?
Is there any other OS's that are not WIN or MAC and use the "\r" or
"\r\n" ?
If their are, then I can see an advantage of using the PHP_EOL.

Like I said, just a quick question. ;)

When you say "mailers" are you talking about emails? If so then you should
be using "\r\n" at all times since that's what numerous email-related RFCs
specify. If you use anything else then you may find your email gets rejected
by strictly implemented mail servers (rare these days, but it happens).

Incidentally, CR only applies to Mac OS9 and earlier. OSX uses LF due to its
BSD roots. For a near-complete list, see "Representations" here:

hi all,
looking at the code Karl has posted, this code bit is not going to be
a help in setting the 'new line' character in an email body, because
it decides based on the server operating system.

if (strtoupper(substr(PHP_OS,0,5)**=='WIN')) {
> $eol=3D"\r\n";

when sending out emails, the most compatible way is to use "\r\n" as
Stuart has pointed out (plain text emails).

Hello All,
Just so you know, this is not something I made up myself.
It was taken from an online HTML email tutorial.
Also, It has worked for years with no problem and I would still use it,
however I found out about the PHP_EOL and was just curious as to the
difference.

Thanks viraj...

Best,
Karl

You've checked that every single email it has ever sent has been received
correctly at the destination mailbox? The internet is built on RFCs, and
their general principle is "be strict in what you send and liberal in what
you accept" - if it wasn't like that the internet would fall apart. I
encourage you to do your part to do things right, but it's completely up to
you if you don't want to follow the users' manual.

@Stuart,
Actually that is what made me look into the PHP_EOL Stuart. Wanting
to do things right.
Did you not read my initial email? I am not suggesting anyone adopt
my code.
The question was directed to what the differences are so I COULD
learn the right way.
Being that this was something I got off a tutorial from an accredited
website, your saying that to the wrong person.
I went and read the manuals and am here now posting the question so
as to get the right direction.
I have heard the argument and actually agreed. It would be better to
use the PHP_EOL instead.
I have been directed in the right direction. So I will be changing my
code to reflect.

Thank you,

Best,
Karl

A am going to end this thread here. Since it is getting cross-post
responses.

I meant no offence, I was simply responding to your comment: "Also, It has
worked for years with no problem and I would still use it" ...and took it to
mean you would have no issue with using that code, so I thought it worth
pointing out that the standards exist for a reason.

In the name of clarification, the "manual" I was referring to is the sum
total of the RFCs that define the various protocols used on the internet,
not the PHP manual which I believe you think I meant.

Hello Stuart,
After some closer look at the RFC Compliant manuals you suggested,
I have determined that the creator of that code was in fact RFC821
Compliant.
Being that this was a code I found several years ago, RFC822 may not
have been in effect.
This being the reason (I believe) that the creator went with a check
for System OS when determining the end of line characters to use.
Not substantiated in any way, but that is what it looks like to me. I
could stand corrected.

Best,
Karl

RFC821: Simple Mail Transfer Protocol, dated August 1982 (
http://www.faqs.org/rfcs/rfc821.html)

RFC822: Standard for the Format of ARPA Internet Text Messages, dated August
13, 1982 (http://www.faqs.org/rfcs/rfc822.html)

So, unless you started using that code before PHP was created (1995 if we go
back as far as PHP/FI) then no, RFC822 predates that snippet of code.

Further, RFC821 defines the end of lines as CRLF, so the creator of that
code was not RFC821 compliant if it was being used to send commands to an
SMTP server.

From RFC821, MAIL FROM command definition: MAIL <SP> FROM:<reverse-path>
<CRLF>

From RFC822, general header field definition: field = field-name ":" [
field-body ] CRLF

Note the CRLF at the end of both definitions.

Now, technically speaking the body of email messages can use any line
endings they want to, but the headers should use CRLF, and commands sent to
servers should also use CRLF.

One final thing for you to consider... what we've been talking about is
commands and messages being sent to other computers, so what good does it do
to send them in a format that's dependent on the OS of the sending machine?
The standards exist so they are OS-independant, because you usually cannot
tell what OS the computer you're talking to is running.

@Stuart
Ah, then you are right that they were not compliant. The code is not
that old.
Thank you so much for the links and information too. Much more than I
expected.
I did not know that they were sent OS-Independent, but that makes
perfect sense.
Again, please excuse my lack of understanding.
My thought on why I would still use the code was that even though the
SMTP server
would not be OS specific, the email program or browser would be and
that it would format
for the user depending on that program/browser and the OS it runs on.
IE: Thunderbird on PC or Mac Mail; viewing yahoo on Safari Mac or IE
on PC.

Technically speaking, is it not possible to determine with a if {} to
see which catches?
This is probably not the best way to go about formating, just more
for my intuit.
With that code, I did not get any bounce backs or messages pertaining
to ill formatting or "no send no show".
So it didn't seem to be a bad code. Thus I continued use.
But like what was said earlier in the thread, I agree PHP_EOL would
be the best fit.

Thank you for all your input, help and resources.

Best,
Karl
