write file

[eluser]dimis[/eluser]
I am working with a multi language site.
So I want when user add a new language to create a new language folder and file (application/languages) and then edit this file.
How Can I "copy/paste" the folder application/english into application/spanosh for example?
I write

Code:

$server=$_SERVER['/css/'];
die($server);

and there is the error

Code:

Severity: Notice
Message: Undefined index: /css/
