How to write Mysql query to compare variable value with column values and get top highest record or second...

I have table in mysql with few records, so I want to compare value with price column.
- if passing value from variable is less than price column value then get second highest record with product id ="p1"
- if passing value from variable is greater then price column values then get top highest record with product id= "p1"
This my table
id product price
1 p1 2000
2 p2 3000
3 p3 4000
4 p1 2500
if we want to compare ' price ' column with value $var='1800' and product="p1" then output should be second highest record because variable value is less than price column value
output :
id product price
1 p1 2000
but if we pass value $var=5000 for price column and product="p1" then
output should be :
id product price
4 p1 2500

What will be the output when input variable is 2200 and product is p1. Now one product has price (=2500) higher than 2200, and another has price (=2000) lower than 2200.
