session_start(); problem

[Intel]

AFAIK, there's no ordinary way to do that, but there are few workarounds available.

Ask Google about: "Browse Button CSS".

Good luck and productive research.

AFAIK - As Far As I Know - насколько мне известно

If you mean script injection, I prevented it in the following line "...&& in_array($_GET['lang'], $a_languages)" for both $_SESSION and $_GET arrays.

As I've mentioned previously, there's no need to check session vars(because like the database records, session variables and their values must be formed by the script, unlike variables coming from request), except that your code is almost unreadable, and less flexible.

Intel, my code is almost unreadable?!
Dude!!!

No, I meant her code, not yours

What is less flexible about my code? I'd say it's much more flexible than yours, where you used switch case operators for checking the value of every single language. I think it's not so smart to do so.

TasteMyLipstick, switch IMHO is better than if -> elseif -> elseif -> elseif -> else.

Any code is 100% flexible if you can edit it

Theoretically, for example you can't control, if the $_GET['lang'] is defined, or not. You may only surmise, starting from isset($_GET['lang']) conjunct with in_array($_GET['lang'], $a_languages).

Well, it's not a big deal, I think. Assuming that:
First of all, the count of languages is finite, and in handsome majority of cases not greater than 2 or 3. So probably our switch structure will not grow up so much.
Secoundly, you may perform custom actions different for each language.

In addition:
Your code contains useless assignings, checks, script termination, also it outputs HTML code(which, I suppose, is very rough for back-end layer) ...
