Need help: selector script

Can someone please help me where to find or how to make selector script, for ex. like this one:

thanks!

I don't know if this is using a database or what but if you want a database to be used in this porcess I suggest the mysql "like" function. Search that on google.

ok, thanks!

and without database, like list of answers?

Well, it depends if you were searching your site or a search engine. Both ways would be pretty complex. If you were searching the site I would take the glob function and the file_get_contents function and get every single file. Then I would take the similar_text function and see which match the result. After that I'd fetch the result and display it on the page. And if you were searching a search engine such as Google I don't know what you would do.

I hope this helps,
Nile

I think I'll manage to do something with that!

Thanks

Tell me what you come up with, I'm interested what you can do with the idea.
