PHP Chmod directory one level up

Hello,

I need to chmod a directory that is 1 level up.

I tried :

system("chmod -R 755 \"../directory\"");

PHP:

but it does not work. Any suggestions?

 

chmod("../directory", 0755);

PHP:

Give that a go.

 

That would not work because PHP didn't create that folder. Just tested it and as always : Operation not permitted.
When using system chmod it can chmod any folder, no matter who created it.

 

For some reason, this works for me:

<?php
system("chmod -R 755 ../directory");
?>

PHP:

 

Does not work at all for some reason, even for directory on same level.

 

Hmm, any ideas? I would be very grateful is someone could help.

 

If you use chmod from the command line does it work?

 

exec('chmod 777 ../directory');

PHP:

Try that

 

exam, it worked on the folder in same directory, so server allows to CHMOD.

danx10, No, does not work.

 

chmod("../directory", 0755);

 

Try chown.

 

Probably a restriction your host placed on you or security settings on your server because I can totally do anything with system, exec and chmod functions. It's best to ask them.

 

Quote from the documentation:

 

Try this:

system("chmod -R 755 " . realpath('./../directory'));
// or 
chmod(realpath('./../directory'), 755);

PHP:

 

How about checking if the directory exists? First and foremost, you must have sufficient privileges on the directory above on which you would like to CHMOD.

Something like:

if(is_dir("../directory")) // Make sure we exist
    chmod("../directory",0755); // CHMOD should work on *nix _ONLY_ unless you're using some Widnows' emulator for it

PHP:

If you're looking to do a recursive CHMOD on the directory and its contents, you're going to need to use a loop. Simply opendir(); and readdir(); and chmod appropriately on all files without name "." or ".." That should work if your PHP is properly setup.
