"log in" to write files

[spelltwister]

I'm not sure if this goes here, but...

Is there a way to add something to my php script that will make it act as though it is the server.

Here's what I mean:

I have a script that generates XML files. I want to have users upload xml to post XML to that script, which I then parse and generate xml with. However, due to permissions, I cannot write the file (I don't wanna open it to all users (777)). Is there a way that my script could be considered the owner?

Also, I'm not really sure about the groups permission. What are groups and how can I use them?

Thanks,

Mike

if you have write access but want to restrict the user access then have a look at umask()or chmod().

php will write files using the user credentials of the process under which it is running (typically the apache user: nobody). to change the file owner, use chown()

if you need more a granular approach i'd suggest using the ftp functions from within your script to open up an ftp link under the relevant user credentials and then upload the file to the relevant directory.

of course to use chown you need superuser authority.
