Reading barcode from webcam in PHP web application

Question

Want to add following feature to my web application: To decode barcodes generated by this script . with webcam and use values in PHP web application.

Is that possible? if yes how?

Answer 1

Not with PHP, seeing as it is server side. But, you could accomplish this with java, javascript, or some other client side languages.

javascript (jQuery) webcam plugin

EDIT -- how this would be done is to take the picture with javascript, and then send it back to the server to decode by PHP.

Answer 2

I happened to come across a project where someone actually accomplished this in a pretty nice way using Javascript:

It only handles a few types of barcodes, but it may be a good starting point if you need the others. You can most likely have Javascript post these back to PHP using AJAX or have them update a form field to be submitted.
