Description:
------------
When I open a file with the b flag in it. for example bw I get the error that the file does not exists. That is correct and I want fopen to create the file for me and set the pointer on the beginning of the code. that is why I use the w flag. I have used the b flag because of the note that is underneath the fopen manual file on the site./

Reproduce code:
---------------
$fp = fopen($this->_file, "bw");

Expected result:
----------------
A new file created in /tmp/12 called foo2.txt

Actual result:
--------------
Warning: fopen(/tmp/12/foo2.txt) [function.fopen]: failed to open stream: No such file or directory in /Users/jason/Sites/zf/myclass.php on line 168
