lorem.example.com/en – should be interpreted as – lorem.example.com?lang=en
lorem.example.com/de – should be interpreted as – lorem.example.com?lang=de

here is my try, without success

RewriteEngine ON
RewriteRule ^(en)/?$ $1.php [QSA,NC,L]  
RewriteRule ^(de)/?$ $1.php [QSA,NC,L]

pls help

>Solution :

You may use this rule:

DirectoryIndex index.php
RewriteEngine On

RewriteRule ^(en|de)/?$ index.php?lang=$1 [QSA,NC,L]

Here:

DirectoryIndex is useful (if not defined in Apache config) to serve index.php when request is just http://lorem.example.com
(en|de) matches and captures en or de in $1, that is used as value in lang parameter.
