Two Different Header two languages

[PaulaSinner]

It doesnt works here
I don't understand how to fit it into different languages...

if($_GET['cPath']) {
  switch($_GET['cPath']) {
   case $template_dir = "layout2"; // thelayout i want to open inside portuguese site
      break;
   
  default: // If none of the above 
  $template_dir = "layoutsah"; // the layout i want to open inside english site
      break;
    }
  } 

??? but it don't make any sense to me
