You can use file to retrieve the contents of Inwine.txt.  You can loop through each row with foreach, and use explode to separate the values.  You can use sort or rsort to sort the array.  max and min to find out highest and lowest prices.  You can use array_sum and count to find out average price. You can use file_put_contents to put the info in Output.txt

 

Good luck!
