How to match a rewritten URL string with hyphens to a string that might have 1 hyphen in MYSQL?

I'm rewriting a URL with hyphens using item_name column. for instance animals of the planet-v9 to http://example.com/book/animals-of-the-planet-v9 with str_replace(' ','-',$item_name). How I'm approaching back to MySQL is:

$item_name = str_replace('-', ' ', $_GET['item_name']);
SELECT * FROM table where item_name LIKE '% $item_name %'

"animals-of-the-planet -v9" Becomes "animals of the planet v9 "

URL: example.com/animals-of-the-planet-v9

The above query matches 0 results, I noticed any of column that contains hyphen - is not matching because sometimes it needs one original hyphen other than the rewritten ones in string. I also tried with = and LIKE in query. How do I figure this out where I can have a pretty simple URL containing hyphens without any numeric ids?

Try this,

$item_name = $_GET['item_name'];
SELECT * FROM table where REPLACE(item_name, ' ', '-') = '$item_name'

Note - Escape $item_name before using it. To prevent your query from mysql injection.
