  • relative path only contain 'chapter02/orders.txt' this path only – Amit Gaud Jun 01 '17 at 12:26
  • Thank you! Avril. I figure it out now. #3 "$document_root..orders.txt" or #4 "D:/wampProject/"."../orders.txt" direct to the parent directory of the apache web root(D:/wampProject/).Thus the orders.txt in D:/orders.txt was written by both paths. PS:I'm an amateur. – Q.Chen Jun 01 '17 at 15:24
