 New Comment:

That is correct; fopen was changed to work in binary mode by default in
order to be more portable.



I thought this was mentioned in the NEWS file, but apparently not.



The change was made in PHP 4.3.2.



The undocumented 't' mode has been a feature of the MSVCRT

since forever.



This stuff needs documenting fairly prominently.

Windows offers a text-mode translation flag ('t') which will
transparently translate \n to \r\n when working with the file. In
contrast, you can also use 'b' to force binary mode, which will not
translate your data. To use these flags, specify either 'b' or 't' as
the last character of the mode parameter. 



As of PHP 4.3.2, the default mode is set to binary for all platforms
that distinguish between binary and text mode. If you are having
problems with your scripts after upgrading, try using the 't' flag as a
workaround until you have made your script more portable as mentioned
above.

Description:
------------
Using mode "r" to fopen files under Windows doesn't open them in text
mode (as it should), but in binary mode, thus working exactly like
"rb". Reading these files, you'll get "\r\n" instead of "\n" for new
line character.



Surprisingly, fopen accepts mode "rt" which isn't documented but works
as "r" should. It opens in text mode and returns "\n" instead of
"\r\n".

Reproduce code:
---------------
Create a file named dat.txt containing 4 bytes: "1", CR, LF, "2", LF.



$f = fopen("dat.txt", "r");



$d = fread($f, 1);

echo ord($d) . " ";

$d = fread($f, 1);

echo ord($d) . " ";

$d = fread($f, 1);

echo ord($d) . " ";

$d = fread($f, 1);

echo ord($d) . " ";



fclose($f);

Expected result:
----------------
49 10 50 10

Actual result:
--------------
49 13 10 50
