I am a php developer. I want to say I didn't tried scanning finger print before using php.
but what i know is if your device support something like saving fingerprint as image automatically then it may be possible to get image data to text file. or if your device has fingerprint scanner api document then it can be done.
Otherwise I need to buy license from flexcodesdk for you with which u need to install some software/driver first on you windows system, then i can use the php library and configure / code for getting data from device to text file or db.
or you want something else let me know or discuss.
