I have a situation where I need to use network card's address for Serial generation. Is there any function for this in PHP .. also if I happen to find or make one how can I make sure that this is available in every php page like environment variables.
One solution is to save it in a file and then include that file in every page, but there is one big problem with this, what if network card is changed then we will have to update that file again, also if application is installed on differnt machines then this will have to be modified for every machine.
Thanx in antiticpation.
