Dynamic translation

Hi Everyone,
I use wp-globus for the translation.

It gives me the option to write all the static pages in 2 different languages. But my main page is highly customized from the php source code and there is no option to translate the main page in wp-globus and this is normal because the main page content is directly edited in the index.php.

I would like to create a condition on the file index.php and also the header.php file that will detect the language from the wp-globus trigger variable or directly from the URL(because when wp-globus switchs to another language, i writes an url like https://www.site.com/wordpressdirectoryname/AR where AR is the language code.

So what i need is something like

<php [php detects language] ?> <php [if $language==AR] ?>
Display text and images in AR language using html.

<php [else] ?>
Display english content in HTML

<php [endif] ?>
