This is reproducable, though very odd.

I have a script that does this:

mkdir("fandelem",0777);


which when I issue 'ls -la' produces:
drwxr-xr-x    2 apache   apache       4096 Oct  4 11:16 fandelem

However when I add:

chmod("fandelem",0777);

which when I issue 'ls -la' produces:
drwxrwxrwx    2 apache   apache       4096 Oct  4 11:19 fandelem

-------------

I don't really understand why -- and I guess I could just have the code do an extra chmod() but I found it quite odd that this happens.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

The mkdir call is affected by umask. Since on most systems (unix) default umask is 022 when it is applied to mode 0777 you get 755 directory permission.
To avoid this problem, do a call umask(0), before creating a directory.
