.htaccess Handle uri with php

Question

I have a codebase that uses the logic,

  if($_SERVER['HTTP_HOST'] == 'fr.example.com')
    {
        $_SESSION["lang"] = "fr";
    }
    elseif($_SERVER['HTTP_HOST'] == 'en.example.com')
    {
        $_SESSION["lang"] = "en";
    }

I want:

www.example.com should serve english

www.example.com/fr should serve french.

All the text is served from the database.

How can I use same index.php to serve english and french content based on what language is there in the URI?

Since you want to handle this in PHP anyway, there is no need for an .htaccess file. Just use $_SERVER['REQUEST_URI'] , eg

$uri = $_SERVER['REQUEST_URI'];
if (stripos($uri, "/fr/") === 0) {
    // handle french
} elseif (stripos($uri, "/de/") === 0) {
    // handle german
} else {
    // handle english
}
