i want to make a script in php that identify the pc. actually i want to make a script like antivirus software which can only install at one pc. if we want to install it on other pc it cant. and also if we install it on same pc after formating complete harddrive it will install, but on any other pc it will not install.
i want to make a script which check that the programme will install only on same pc every time after formatting. but if it is not same pc it will not work.
