problem setting permisions

[harvey]

I'm not sure if this is a linux, apache or PHP problem but I'm using PHP
to do it so I'll start here:

if I do
$myDir = '/temp/';

mkdir($myDir,0777);
chmod($myDir,0777);

I get a directory with 777 permissions. That seems fine.
(The chmod seems needed to undo a mask)
The directory is created with owner & user as Apache

However if I now do:
if (!mkdir($myDir . 'subDir/',0777)) {
echo('Creation error');
}
chmod($myDir . 'subDir/',0777);

I've tried removing the trailing slash to no effect.

PHP fails to create subDir/ at all AND doesn't flag up the error.
I expect I'm missing something fundamental but can't see what.

Can anyone help please?

Maybe to do with the trailing '/'
Have a look at the user comments at:

Thanks for that heads up -
Surely someone has a simple solution for this that will work anywhere?
Using FTP (as suggested) just seems absurd to me.

After reading the above link I think I can sumarise with:
-----------------[ CUT ]------------
If you're on a shared *nix server, a directory created through mkdir()
will not be assigned to you, but to the user that your host's server or
php process is running under, usually 'nobody', 'apache' or 'httpd'.

In practice, this means that you can create directories, even add files
to them, but you can't delete the directory or its contents nor change
permissions.

-----------------[ END CUT ]------------

It is also incomplete - it appears you cannot create sub-dirs in them
without taking extra steps ... using umask() and sticky bits depending
on configuration. And even then it doesn't always work nor report
the failure.

All this can't be right can it?

If I am not overlooking something obvious, if apache:apache is the dir
owner, your script should be able to make a subdir in it, since the script
operates as apache:apache.

However it may be a problem accessing these dirs via FTP (other user:group)

I suspect we are both overlooking something - I'm having great trouble
making this work.
