Does a fopen with 'b' mode suppress magic_quotes_runtime ?

[flconseil@yahoo.fr]

Hello,

The PHP documentation contains a user note which says that opening a
file in binary mode ('b' flag) replaces the need to set
magic_quotes_ru ntime to off before every read and writes.

As it seems not to correspond to the rest of the documentation (I
thought that the 'b' mode was used only for Windows end of lines), can
somebody please tell me if it is right or wrong ?

I am developping a library which needs to read binary data from files
and, as I have to deal with a possible setting of magic_quotes_ru ntime
to on, it would make it much simpler if it could be specified at
fopen() time.

Thanks in advance

François

b is for binary. When you open for example an image you should put b on.

From the manual:
If you do not specify the 'b' flag when working with binary files, you
may experience strange problems with your data, including broken image
files and strange problems with \r\n characters.

As far as I know it has nothing to do with magic_quotes_ru ntime

Opening a file with 'b' does not suppress magic_quotes_ru ntime. If it
is turned on, then file(), fread(), file_get_conten ts(), and others
will add slashes to their results.

Do people really use magic_quotes_ru ntime?

OK. Thank you. I just had a doubt because of this strange comment from
'tilman DOT schroeder AT gmx DOT de' on
http://www.php.net/manual/en/functio...es-runtime.php.

I don't know if people use this f... option, but if I want to be able
to run everywhere before PHP 6 suppresses this option, I must take it
into account. And, if I want to be compatible with PHP 6, I must check
the PHP version before calling set_magic_quote s_runtime().
