Continual "undefined index:day" errors in PHP script

This is my script, which is intended to show a different page depending on day of the week.

PHP Syntax (Toggle Plain Text) 
  1. <html>
  2. <? error_reporting(E_ALL);?>
  3. <body>
  4. <?
  5. $i=$_GET['day'];
  6.  
  7. switch ($i) {
  8. case 0:
  9.     include("2.php");
  10.     break;
  11. case 1:
  12.     include("3.php");
  13.     break;
  14. case 2:
  15.      include("4.php");
  16.     break;
  17. case 7:
  18.       include("5.php");
  19.     break;
  20. default:
  21.     echo "page not found!!!!";
  22. }
  23. ?>
  24. <?php
  25. $d=date("D");
  26. switch ($d)
  27. {
  28. case "Mon":
  29.     include("2.php");
  30.   //echo "Today is Monday";
  31.   break;
  32. case "Tue":
  33.     include("3.php");
  34.   //echo "Today is Tuesday";
  35.   break;
  36. case "Wed":
  37.     include("4.php");
  38.   //echo "Today is Wednesday";
  39.   break;
  40. case "Thu":
  41.     include("5.php");
  42.   //echo "Today is Thursday";
  43.   break;
  44. case "Fri":
  45.     include("6.php");
  46.   //echo "Today is Friday";
  47.   break;
  48. case "Sat":
  49.     include("7.php");
  50.   //echo "Today is Saturday";
  51.   break;
  52. case "Sun":
  53.     include("1.php");
  54.   //echo "Today is Sunday";
  55.   break;
  56. default:
  57. //echo "Wonder which day is this ?"; 
  58. }
  59. ?>

When I run it, it partially works, but this notice appears at the top of the browser:
Notice: Undefined index: day in C:\www\vhosts\mywebsite1\dayweek.php on line 5

I would appreciate any advice anyone has on fixing this, since I always get the undefined index error, which makes the site not function properly.

Thanks

$i=$_GET['day']; will cause the notice if you call the page without this parameter. To remove the notice, do this: $i = isset($GET['day']) ? $_GET['day'] : -1;

the switch should have '{' opening brace and not the closing brace '}' . that's why there's that syntax error.

the closing brace in line 57 is commented out, put it on the next line.
