Thank you for your post. Unfortunately, the current build version
(php6.0-win32-200802041530) did not cure the issue.

Description:
------------
Using FILE, when the parameter FILE_IGNORE_NEW_LINES is used, if the
file uses a line termination of \n the operation works as expected.
If the file uses a line termination of \r\n (MS Windows), the \r is not
removed.
One might argue that the NEW_LINES is \n alone, and of course FILE works
fine when the file has a \n terminator, however, \r\n is a common line
record (line) terminator on a windows system. If memory serves, this
kind of issue has been addressed in some other PHP functions, so it
would be great if you would consider addressing this one too.
The problem really becomes apparent if you take two arrays derived from
FILE functions and combine them via an array_combine.
Reproduce code:
---------------
/* create 2 files in notepad.
$somefile1 data:
foo
bar
etc
$somefile2 data:
123
456
789
*/
$a1 = file($somefile1, FILE_IGNORE_NEW_LINES+FILE_TEXT);
$a2 = file($somefile2, FILE_IGNORE_NEW_LINES+FILE_TEXT);
$a3 = array_combine($a1, $a2);
print_r($a3);
Expected result:
----------------
$a3 is an array with three entries with both key and data each entry
having a length of 3 bytes.
Array
(
[foo] => 123
[bar] => 456
[etc] => 789
)
(which is what happens when a file contains \n terminated lines).
Actual result:
--------------
$a3 is an array with three entries with both key and data each entry
having a length of 4 bytes.
Array
(
[foo
] => 123
[bar
] => 456
[etc
] => 789
)
(which is what happens when a file contains \r\n terminated lines).
