Re: How to get server user?

It is not obvious to me... Can I get that from an $_ENV or $_SERVER value? I have a web base cms system with a file editor and want to test for ownership of the files and directories without having to hard code the server name. I can get file owner ship but if I want to verify it is the server user account, I would do: (pseudo code) $_name = getOwner() if($_name == < portable reference to server user name>) { // proceed } This would be for enhanced access permissions analysis. If a file is being written to by the server user (via php code) it would be helpful to determine that to forstall error message generation. I can’t be absolutely certain it would universally work, but this should work on most platforms: $user = trim(whoami); Alternatively you could use http://php.net/tempnam to get a temporary filename, create and close it, then get the owner details. However, as mentioned previously you should really be dealing with errors in a sensible way. If your script has reason to write to a file it should attempt to do so and deal with a failure. Pre-emptive programming should never take the place of defensive programming. -Stuart --  Stuart Dallas 3ft9 Ltd http://3ft9.com/
