chmod (PHP 3, PHP 4 ) chmod -- Change le mode du fichier. Descriptionint chmod ( string filename, int mode)
chmod() remplace le mode du fichier
filename par le mode mode.
Il est à noter que le mode mode est
considéré comme un nombre en notation octale. Afin de
vous en assurer, vous pouvez préfixer cette valeur par un
zéro (mode):
chmod() renvoie TRUE
en cas de succès, FALSE sinon.

chown() et
chgrp().
Note :
chmod() ne fonctionne pas sous Windows.

Usually when you're trying to write to af file, you'll need to chmod the
file to something like 666 or 755. You can use a command to chmod the file
for you, which is especially useful when you're making a script where
you're setting it up so that your users don't have to peform a bunch of
actions to setup the script. When i wrote my news program script, I only
had two files. install.php and config.php. All you had to do was chmod
install.php to 666 and open it up in a web browser and answer a few
questions. The script itself setup the rest of the files and chmodded them
for you.

if 'mode' is held in a variable and is and octal value you need to convert
it to decimal before passing it to the function:
chmod ($filename,
octdec($mode))

It does work on Windows.
I use Win 98 with the Sambar Server.
The
only chmods allowed are the 775 and 666 mod. 775 for non-writeable and 666
for writeable. The only thing is that the usergroups doesn't
work.
Note: the 0 at the start doesn't work with windows. use only the
decimal kind.
Have fun :)

For those not so familiar with UNIX file modes, this might be
helpful:

Again,
never forget that the file mode must be passed as an *octal* value, not as
a decimal number or a string. So it must be 0755 instead of 755 or
"755", for example. This is a very common pitfall.

This function is very often disabled by the hosting services company.
So
it is quite impossible to make an upload when you can't change the rights
on a file.

[Editor's note:
That is due the fact Win32 systems treat premissions.
You do not really have any other levels but
read-only.

On WinME with apache chmod also
works to a certain limit.
What happens is that apparently only
the first number is counted, so 0666 (read-write) is the same as 0777,
0644, 0600, etc, and 0444 (read-only) is the same as 477, 400,
etc.
..didn't test 0500 series

Be careful with in the function chmod ( string filename, int mode),
"filename" must be contain the full path of the file.
Ex
:
chmod ("../file", 0755) won't work.
chmod
("/somedir/somefile", 0755) will work.
