#41609 [Csd->Bgs]: file_put_contents() injects \r

The FILE_BINARY flag does fix the problem. I'm closing this. ------------------------------------------------------------------------ [2007-06-09 21:17:40] pajoye@php.net "when files are not opened with the binary flag, windows automatically converts \n to \r\n. I don't have time until mid-July to investigate this problem though." As far as I remember, it is the documented behavior (windows file functions). It is especially important to take care of text contents in the unicode mode, it is not a good idea to blindly save everything as binary. That's why php6 has two new flags which can be used in file_put_contents: - FILE_TEXT, opens with "wt" (or "at" if FILE_APPEND is used) - FILE_BINARY, opens with "wb" (or "ab" the default mode is "w", which is a text mode on windows. I do not have a windows at hand to test but I'm pretty sure that FILE_BINARY solves your issue. It may use it automatically when a binary string is given, but I would find that trickier (magic++). ------------------------------------------------------------------------ [2007-06-09 21:03:19] nlopess@php.net when files are not opened with the binary flag, windows automatically converts \n to \r\n.

Does something like <?php $a = "foo\nbar"; var_dump((binary)$a); ?> also show the \r? ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
