Our website in php and backend in mysql.
we have to get serial number of client pc ( hardware id i mean motherboard serial) when any user get logging first time.
Now we are authenticating using ip , but we want get the serial number of client pc, I have a field in mysql table pc srical number.
now we want update serial number field when client logging first time
so we need a script(or anything) that can get client ip and update the pc serical number field in mysql if no data is present in this field. If the client logging different pc he may get an alert message and an email will forward to client registered email id with and link, upon clicking this link again the serial number field will update with new pc then the client can login using new pc .
