I have a php code here and I would like to create a "back" href to get me back to where I was before. Here's what I have:

<input type="submit" <a href="#" onclick="history.back();">"Back"</a>

     <html>
     <head></head>
     <body>

     <?php
     // get form selection
     $day = $_GET['day'];
     // check value and select appropriate item
      if ($day == 1) {
      $special = 'Chicken in oyster sauce';
         }
      elseif ($day == 2) {
      $special = 'French onion soup';
       }
      elseif ($day == 3) {
       $special = 'Pork chops with mashed potatoes and green salad';
        }
      else {
      $special = 'Fish and chips';
      }
      ?>

      <h2>Today's special is:</h2>
       <?php echo $special; ?>
       <input type="submit" <a href="#" onclick="history.back();">"Back"</a>
       </body>
       </html>

In my application,above javascript function didnt work,because i had many procrosses inside one page.so following code worked for me hope it helps you guys.

  function redirection()
        {
           <?php $send=$_SERVER['HTTP_REFERER'];?> 
            var redirect_to="<?php echo $send;?>";             
            window.location = redirect_to;

        }

Basically my code sends data to the next page like so:

**Referring Page**
$this = $_SERVER['PHP_SELF'];
echo "<a href='next_page.php?prev=$this'>Next Page</a>";

**Page with button**
$prev = $_GET['prev'];
echo "<a href='$prev'><button id='back'>Back</button></a>";
