    That tells PHP to ignore those quotes. Without them PHP tries to parse them and therefore the script errors out.

    the { } tells PHP that everything inside the curly brackets should happen if ($thispage != "Home")

    This is useful if you want to have more than one command in your if statement. In this case it's not really NEEDED because there's only one command after the IF statement. But it's good coding practice to use it. :)

    but we can use elseif syntax to have more commands..
    why did u write { } ?? is there any special use of it?

    Technically you do not need them for a single line, but they are a good coding practice. The brackets tell the PHP parser where to start and stop, in this case the if statement.

    For good clean clode it is best to use line breaks to separate the code. 

    <?php 
  $thisPage="Home"; 
?>
<html>
  <head>......</head>
  <body>

  <?php 
    if ($thisPage!="Home") {
      echo "<div class=\"footer\"> 
      <a href='javascript:history.go(-1)'> [ Back ]</a> 
      </div>"; 
    }
  ?>

  </body>
</html>

    if you had more complicated code, it would be useful. else or elseif commands only happen if the condition in your IF statement is not true. so for example:

    
<?php 
     if ($thisPage!="Home") 
     { 
          echo "<div class=\"footer\"> <a    href='javascript:history.go(-1)'> [ Back ]</a> </div>"; 
          $some_variable = 0;
     } 
     else
     {
          echo "Next >>";
          $some_variable = 1;
     }

?>

    Will it work your way, yes it should.
    Is it a good coding practice, no.

    Oh, I see... yes, your code should work both ways, but it's bad coding practice to not use the brackets. It's a bad habit that could cause confusion for you or anyone reading your code in the future!

    hmmmm... that's strange. try this:

    
<?php $thisPage = "Home"; ?>
<html><head><body>
<? 
     if ($thisPage != "Home") 
     { 
          echo "<div class=\"footer\"> <a href='javascript:history.go(-1)'> [ Back ]</a></div>"; 
          $page = "not home";
     } 
     else
     {
          echo "Next >>";
          $page = "Home";
     }

?>

<? echo $page; ?>
</body></html>
    PHP:
    It's exactly the same as what you posted, just with some spaces added in the code... I'm not sure why that wouldn't work. Anyone else?

    Oh sorry, it's not necessary, since you're just echoing the contents of a variable.
