Php file creation doesn't work

Question

My webserver is run as daemon . I know about security and so on but please ignore this for now. My problem is that I've done:

> chmod 777 /web/htdocs/olivier/wogwog/transit/02.done
> ls -al /web/htdocs/olivier/wogwog/transit
drwxrwxrwx 2 hqfdev hqfdev  36K Jan 17 14:41 02.done

So the directory belongs to user hqfdev / group hqfdev . Here's my Php code:

$tmp_name='/web/htdocs/olivier/wogwog/transit/02.done/caca.txt';
if (($handle=@fopen($tmp_name, 'w'))!==false) {
    fclose($handle);
    error_log('OOOOOOOOOK');
} else {
    error_log('error');
}

I keep getting this in my logs:

[snip] [:error] [snip] current running = daemon, referer: http://www.blabla/
[snip] [:error] [snip] PHP Warning:  fopen(...): failed to open stream: Permission denied in /blabla.php on line 5, referer: http://www.blabla/
[snip] [:error] [snip] error, referer: http://www.blabla/

So the process that tries to create the file is daemon and it cant write to a 777 folder that belongs to hqfdev . (*.*) . I'm totally stuck because I've done this a billion times and it worked. For your information, if I ssh my server, log in as hqfdev and launch that script "by hand", it works. What could be the problem (and of course the solution)?

Answer 1

I've found the solution: the parent folder didn't give the right to its children:

Configuration that doesn't work

$ ls -al /web/htdocs/olivier/wogwog
drwx------ hqfdev hqfdev transit
$ ls -al /web/htdocs/olivier/wogwog/transit
drwxrwxrwx hqfdev hqfdev 02.done

---

Now the configuration that works :

$ ls -al /web/htdocs/olivier/wogwog
drwxr-xr-x hqfdev hqfdev transit
$ ls -al /web/htdocs/olivier/wogwog/transit
drwxrwxrwx hqfdev hqfdev 02.done

...pure Unix lack of knowledge...
