First of all, never use uninitialized variables. Even if you think
this is o.k. if(!isset($_SESSION['counter'])) $_SESSION['counter']=0; is
not hard code but now you don't depend of session vars behavior modified
with every PHP version.

Will never increment it because of post-increment.
I think you mean this:
$_SESSION['counter'] = $_SESSION['counter']+1;
