Windows fixes release for Zip, fopen(,"rb") may not be binary safe

Posted by Pierre in PHP

This release is mostly for windows users using other SAPI than CLI or (F)CGI. The bug is fixed in CVS already but I was lacking the time to release it. Pecl4win providing snapshots, it is half of a problem :-)

The issue is actually a windows bug. No matter if I give or not the "b" flag to fopen, the write operations are not binary safe. It seems to be a known issue as many projects use the same trick:

 _setmode(_fileno(tfp), _O_BINARY );

PHP is forcing the binary mode in SAPI and CLI, that’s why the problem was not that easy to reproduce (apache or IIS debuggin on windows was not really my cup of tea :-).

I was trying to find some reference or bug reports about this issue but without much success, so far only people complaining about windows broken fopen. If anyone has detailed informations about this issue, please let me know.

As always you can fetch the DLLs from pecl4win or PECL.
