Getting unknown urls in Crawling errors?

[Anjanasai]

When ever i am checking crawling errors on google webmaster tools, it shows some unknown urls which are not in my website.
example links:
http://www.example.com/shopbrand/004/002/X
http://www.example.com/shopdetail/003003000022
http://www.example.com/shop/shopbrand.html?search=&prize1=%83T%83%93%83z%83%8F%83C%83g
http://www.example.com/shop/basket.html
http://www.example.com/shopbrand/ct608

Here /shopbrand, /shopdetail, /shop , /shop/basket urls are not in my website. why i am getting these urls in crawling errors?

Sometimes Google crawl and giving us unknown urls like that because of its queries.
You need to do a 301 redirection for wrong urls or blocking Google spiders crawl these URLs with robots.txt

Is it what you call broken link? Or dead link? You need to remove them if they are no longer required.

Better ask your developer to write the PHP redirect code to redirect the unwanted URL to reach the 404 error page for Search Engines and Users.
