The first scanner is an RS-232 one. You'll need to catch the incoming
data off the serial port. There's a "php-serial" class out there, but
I've never had a use for it, so I don't know much about it.
The second can have a keyboard wedge and thus requires no special
programming. You'll just pretend that someone using the scanner typed
the barcode value. Unless the customer has only an RS232 for the
scanners, in which case you're back to the class above.
