php for............. wat site/something

It's C++ , not PHP.

Yes that is a good method but another could be using NtQuerySystemInformation, although you will still have to read the process's Access Token to find out the user's SID and convert it to the user.
The PEB and TEB also contains a lot of useful info

Other methods could include:
_EPROCESS Kernel block reading (With Debug APIs)
Process32Next (Snapshot API)
EnumProcesses
