Outputting data in CSV format is not hard. Simply echo the header row if
necessary, followed by \n. Then output each line taking care to put
string values in quotes which means you also need to escape quotes in the
data. After each line echo \n. That's really all there is to it.

Jason, one of the points that Stut was trying to explain is that \n
and chr(10) are the same thing. They are just two different ways to
refer to a newline (line feed) character. Most of us probably use \n
rather than chr(10) in PHP, though. So, the following two lines are
equivalent:
?php
echo Item1, Item2, Item3 . chr(10);
// Note this uses double quotes.
echo Item1, Item2, Item3\n;
// It won't be the same at all if you use single quotes
echo 'Item1, Item2, Item3\n';
?
At any rate, you are correct that you need a line feed/newline
character at the end of every row in CSV including the header row.
Andrew
A line feed and \n are not the same thing at all. Different operating
systems implemented a different method of line endings depending on what
they thought best, either a carriage return or line feed or both. a \n
is meant to be an OS agnostic way of implementing this in the various
programming languages, outputting something that any OS can understand
in the intended way.

As I understood, \n was strictly a line feed (ASCII character 10), not
an OS agnostic end-of-line terminator. It happens to be the line
terminator for *nix. Windows uses the combined carriage return and
line feed characters (ASCII characters 13 and 10) which are
represented by \r\n in PHP, while Mac used only the the carriage
return. There is a PHP constant PHP_EOL that I'm pretty sure is
supposed to represent the line terminator defined on the operating
system of the computer executing the script, but I don't think it is
truly agnostic either. At least, if you have a text file saved in
Windows and split it on a Linux machine based on PHP_EOL, I believe
all of your array values will have a carriage return character hanging
on the end of them. Am I mistaken?

I'm afraid I do disagree with your there:
When writing a file in text mode, '\n' is transparently translated to
the native newline sequence used by the system

Interesting. I didn't know it behaved differently when writing files.
I just know that when using it as a search pattern or for splitting
text that it is only the newline character. I thought the behavior you
are describing was specifically why PHP added PHP_EOL. Further down
the same article it says:
Some languages have created special variables, constants and
subroutines to facilitate newlines during program execution. One
example is the PHP constant PHP_EOL, which will produce either '\r\n'
or '\n' appropriate to the operating system the program is executed
on.[3] Though special newline handling facilities can aid execution
during runtime, they do not ensure the validity of newlines for the
source code itself.
I guess since PHP is written in C it picks up the behavior you
describe from the underlying libraries. That's definitely interesting
to keep in mind.

[PHP] CSV Files
Hi All, I need to take a record in MySQL and have my user get it as a CSV File. I am OK with most everything, except when I create the CSV file, I write out the column headers then I need to write out the data. After I right out the column headers do I have to put a '/n' to have it start a new line in the CSV file? I think I do. Here is what I have (a snippet): header(Content-type: application/csv); header($filenameString); header(Pragma: no-cache); header(Expires: 0); echo $map_BORROWER_FIRST_NAME., ; echo $map_BORROWER_LAST_NAME., ; echo $map_BORROWER_SSN., ; echo $map_BORROWER_HOME_PHONE., ; echo $map_BORROWER_DOB; echo /n; echo $row[BORROWER_FIRST_NAME].,; echo $row[BORROWER_LAST_NAME].,; echo $row[BORROWER_SSN].,; echo $row[BORROWER_HOME_PHONE_FIRST].$row[BORROWER_HOME_PHONE_MIDDLE]. $row[BORROWER_HOME_PHONE_LAST].,; echo $row[BORROWER_DOB_MONTH].$row[BORROWER_DOB_DAY]. $row[BORROWER_DOB_YEAR]; When I run this, I see my column names, but not the data.

Jason, one of the points that Stut was trying to explain is that \n
and chr(10) are the same thing. They are just two different ways to
refer to a newline (line feed) character. Most of us probably use \n
rather than chr(10) in PHP, though. So, the following two lines are
equivalent:
?php
echo Item1, Item2, Item3 . chr(10);
// Note this uses double quotes.
echo Item1, Item2, Item3\n;
// It won't be the same at all if you use single quotes
echo 'Item1, Item2, Item3\n';
?
At any rate, you are correct that you need a line feed/newline
character at the end of every row in CSV including the header row.
