Code:

useradd -G group-name username

but i doubt this is your problem as the php is going to run as the apache user right??
and anyone that accesses the page has the rights of the apache user??

what are the permissions for the file being called?

The error message by itself is not sufficient to guess it's cause. With code, you should write a small example script that replicates the issue and is postable.

As far as adding an existing user to an existing group, you'd use usermod. Check out the usermod manual page with man usermod. However, to add the user paul to the group apache, you should be able to use something like usermod --append --groups apache paul or, the short version might be usermod -aG apache paul

Before adding paul to the apache group, verify paul's current group membership with id --groups --name paul or id -Gn paul

After adding paul to the apache group, verify paul's new group membership.

Hope this solves your PHP issue, as well. Good luck.

CentOS,
All I want is user "paul" to write to www directory under which index.php is present.
How can I make it possible?

well as i said, assuming your apache user has write permissions, add paul to the apache group.

does user paul access this via a browser?? if so, i cant see how this makes a diff as the file is called as the apache user..

I am Very Confused..and Let me explain.
I have few files under /var/www/html as:

Code:

ls -la | grep www
drwxrwxrwx  8 root root  4096 Nov 21 03:04 www
cd www
ls -la
total 64
drwxrwxrwx  8 root root 4096 Nov 21 03:04 .
drwxr-xr-x 25 root root 4096 Nov 21 11:07 ..
drwxrwxrwx  2 root root 4096 Jan 16  2008 cgi-bin
drwxrwxrwx  3 root root 4096 Nov 20 12:16 error
drwxrwxrwx  5 john john 4096 Nov 22 08:18 html
drwxrwxrwx  3 root root 4096 Nov 20 12:18 icons
drwxrwxrwx 14 root root 4096 Nov 20 12:18 manual
drwxrwxrwx  2 root root 4096 Nov 20 13:32 usage
cd html
ls -la
total 44
drwxrwxrwx 5 john john 4096 Nov 22 08:18 .
drwxrwxrwx 8 root root 4096 Nov 21 03:04 ..
drwxrwsr-x 2 john john 4096 Oct 30 16:50 bytype
drwxrwxr-x 2 john john 4096 Nov 22 08:08 imgs
-rw-r--r-- 1 john john 3771 Oct 30 16:50 index.html
drwxrwsr-x 2 john john 4096 Oct 30 16:50 js
-rw-rw-r-- 1 john john 9909 Nov 22 08:14 notice.php

Code:

id john
uid=501(john) gid=501(john) groups=501(john),48(apache)

Now Just want to know Does User "john" has write permission to DOCROOT
???

Especially when using a CMS, I set ownership of the html directory to the apache user using

Code:

chown -R apache:apache /var/www/html

Since usually your web server runs as user apache, this gives adequate privileges for running the scripts. I'm sure there's something wrong with that and, hopefully, someone else will add what...

But you don't need the world writeable flag on. To turn it off, use

Code:

chmod -R o-w /var/www/html

I think you can set the sticky bits on the html directory to get new files to get the same ownership by using

Code:

chmod ug+s /var/www/html
