$description is an array. you can list its key/value pairs with var_dump or print_r php functions.

If you are sure "address" holds the value you want to modify and it is like you said most likely there is "<br/>" for each new line in it. You can also use smarty replace on the variable to replace the new line with comma.

Coding modifier you can use "explode" to split the $description['address'] and then joing them together in new variable(s) as you need
