Hi all,
I know seeing this post topic, you will think is a huge of code but looking through it well you recognise its just a pieces of codes integrated to give us what we are looking for. Here every browser has a language its browsing with, now I use PHP to call it out with the $_SERVER function
<?phpecho $_SERVER['HTTP_ACCEPT_LANGUAGE'];?>
the output of that is this en-US,en;q=0.5 because am using English, now we can’t use all this to know the language i will need only the en to know its English, now what are we to do? 
Am going to use the substr() function to delete some letters, here it goes
<?php$language = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 2);echo $language;//you can identify a user's language using thisif($language=='en'){echo"Hello user, you are English!";}?>
The output of that code will just be en
Hope it helps!
