Like said in other mail, don't think apache's file permissions are really
related to file system's permissions as such, but, more to do with apache's
allowing you, as a user accessing files via it's serving channels to perform
certain actions via the access of a file - you can read/retrieve it, execute
the script/code within it, or make changes to it, and thus you can possibly
create a new file in a folder, but, issue is since am not really letting web
browsing identity create an image file, but am using code to copy it out of
temporary upload location to another location, apache is then suddenly telling
me that it doesn't like the fact that I had told it to allow at least
read/retrieval permissions on an image file, or something.
Strangely enough it seemed prepared to let me create .htm files in almost the
same place, from scratch, and retrieve them, but, wouldn't let me copy uploaded
image files to a sub-directory, and then try retrieve them just for reading
thereafter - unless it's something to do with the server having at some stage
assigned some form of executing/processing to image file types, and that's why
it's ow blocking them - I'm not the server administrator as such, but anyway.
Maybe I should test/try out combination of file_get_contents(), followed by
file_put_contents() to virtually create the image files from scratch, adn see
if that's not something triggering this in that I am copying uploaded files
over to serving area of site, or something..?

The .htaccess file is not for changing filesystem permissions (if apache can
even do that). At least on my f19 setup, apache doesn't have the right to do
anything except use the files in the folder tree it was assigned to. Otherwise
it is treated as a rebel process out for no good.

Jacob,
Off the top of my head, can't you make the change permanent using the
.htaccess file?
Best regards,
David.

Hi Jacob,
My memory tells me that Apache runs as a user called nobody. That user has
very little permissions. That is for security reasons. I'm not sure what the
best solution for this is in your scase.
Thanks.

Just posting this here in case someone has an idea about how to 'fix'
this/work around it - since haven't managed to find anything via 'net, or other
PHP specific mailing lists as of yet.
In that small/simple content-management-system posted about other day, issue
seems to be that while am continually/consistently setting output file and
folder permissions to 0776 - owner and group rwx, and public rw - for now -
using PHP's chmod() function, before and after trying to copy/generate any
output content for it, the server seems to be
consistently/dynamically/immediately resetting the permissions to something
slightly different, which won't let me then view/browse all the content.
Silly/simple example is that I will handle image file upload, and copy
uploaded image to a folder in a script, but, sort of immediately, that image,
and the folder it's in, and that one's parent folder are
invisible/unavailable/inaccessible.
Before I then run a sort of recursive script to again reset all content
permissions, I can't even browse the content via FTP interface - for example.
When generating output/static content, I am also then
consistently/continually resetting path permissions just before/after creating
folders and files, if necessary, and that seems to work, some of the time, but,
not for everything.
Am going to try it out on another server, just to try figure/find out if it's
a specific issue for this server/part of file structure, or something, but, bit
irritating thus far...<smile>
Stay well
