Is it possible to obtain facebook likes using just a script?

I want to ask you guys one question: is it possible to obtain facebook likes from all the visitors that enter your website? Someone told me that using a script, the people who visit your website can give you facebook likes without knowing it. It sounds a little bit weird for me, maybe you guys can make it clear.

Regards and thanks in advance. Sorry if it is a stupid question, i am a newbie!

There are ways to do things like this, but you'll perpetually be coding and re-coding as Facebook plugs security holes. You also need to be absolutely brilliant. You probably also shouldn't live in the United States, or you'll get sued pretty quickly. And you'll need to make sure you're using a web host that won't take your site down from a Cease & Desist.

In short, it's probably not a good strategy. There are scripts that can make people like or share things without their consent, but they're very difficult to execute and you open yourself up to a whole host of legal problems.
