writing a homework assignment for some car dealership thing and when i run the program the dos window comes up blank. i dont understand why!

<?php
  $disco = array();
  $sticker = 0;
  $year = 0;
  $code = 0;
  $row = 0;
  $col = 0;
  $percent = 0.0;
  
  $fb = fopen("discount.txt", 'r') or die("\n Can not find file discount.txt\n");
  
  $r = 0;
  while( $r <6)
  {
      fscanf($fb,"%f%f%f%f%f", $disco[$r][0],$disco[$r][1],$disco[$r][2],$disco[$r][3],$disco[$r][4]);
      $r = $r + 1;
  }
fscanf(STDIN, "%d", $sticker);
  fscanf(STDIN, "%d", $year);
  fscanf(STDIN, "%d", $code);
  $row = 2006 - $year;
  $col = $code - 1;
  $discoPercent = $disco[$row][$col];
  $percent = $col * 100;
  $discountAmount = $col * $sticker;
  $salePrice = $sticker - $discountAmount;
  print("\nSticker price: $sticker");
  print("\nDiscount: $percent %");
  print("\nDiscount amount: %discountAmount");
  print("\nSales prices: $salePrice"); 
  fclose($fb);

?>

my data file:

Wait... You're doing this in PHP?? Why is there a DOS window involved?! If you could explain more of it, I'd be happy to answer. The functions you use remind me of C/C++...

when i run the program its supposed to display to the screen instead of a file. so it runs it in the /cmd window. but it comes up blank not quite sure how else to explain it.

Oh. Understood. Well, I don't know why... Could you give me your whole data file in a [ CODE ] [ / CODE ] thing?
