Switch statement in PHP injected HTML

You have

?>\n\n<?

after your switch which becomes

switch($var):
echo "\n\t";
case 1:

Think of your script as PHP with HTML in it, rather than embellished HTML. The PHP binary gets the file first.

You might like to use something like HEREDOC to echo out unescaped HTML.

I read in the php doc that your example should not work.

Any output (including whitespace) between a switch statement and the first case will result in a syntax error. For example, this is invalid

Try this instead:

<div>
<?php switch($variable): 
case 1: ?>
    <div>
    Newspage
    </div>
<?php break; ?>
<?php case 2: ?>
    </div>
    Forum
    <div>
<?php break; ?>
<?php endswitch; ?>
</div>
