Permissions on a mounted NFS share

I am trying to make a php script on a webserver write into a folder /data on a fileserver.
Apache 2.2, PhP 5.x. It's just a test configuration but I'd like to understand the thing somehow as I am not very experienced regarding permissions when it comes to webservers.
I am sharing the folder /data on the fileserver by adding
/data 192.168.20.6(rw,sync,no_subtree_check)
Mount the folder by
sudo mount 192.168.20.5:/data /mnt/data
Create a link to the webroot(does that makes sense at all?)
sudo ln -s /mnt/data /webroot/site1/share
Then I get this:
Warning: fopen(/webroot/site1/share/data/uploads/Fotoraum/Original/Bluehend/test.txt): failed to open stream: Permission denied
Where and how do I have to adjust permissions in a sane manner to allow the script to write into /data and its subfolders?
Thanks a lot!

I suppose the warning is from a webserver? They typically run under a separate user, e.g.www. You mounted usingsudo, hence the mountpoint is owned byroot. Please post the output ofls -ld /mnt/dataandsu <www-user>; touch /webroot/site1/share/foo.txt

btw, using a mounted nfs volume might not be a very good idea: (a) if the fileserver is offline, the webservice stops working (b) network/server latency. Perhaps it's better store the files locally and then sync them over regularily?

make sure that user that is creating a link has ownership ofdatafolder.

@sebastian Doing the ls -ld on the link gives me this lrwxrwxrwx 1 root root 9 Sep 11 21:54 data -> /mnt/data btw the files that we put on the nfs are just the huge original files of the pictures we store. Smaller resized versions are on local storage ;) To behonest, I don't know who the www-user is...

per your comment I think the following option is better than chmod -R 775 /mnt/data
when using mount, you can specify the user and group which owns the files, maybe you want to use the following:
sudo mount 192.168.20.5:/data /mnt/data -o uid=<uid-of-www-data>,gid=<gid-of-www-data>
the values uid and gid of www-data can be found in /etc/passwd and /etc/group.

The uid and gid options do not apply to NFS mounts. (Perhaps you're confusing NTFS?)

You can do chmod 6777 on the shared folder from the nfs server, so that any files being created on the file belongs to the owner group of the folder.
