Hi Daniel,
take a look at this section of the manual about including remote files:
>>>
If "URL fopen wrappers" are enabled in PHP (which they are in the default
configuration), you can specify the file to be included using a URL (via
HTTP or other supported wrapper - see Appendix J for a list of protocols)
instead of a local pathname. If the target server interprets the target file
as PHP code, variables may be passed to the included file using a URL
request string as used with HTTP GET. This is not strictly speaking the same
thing as including the file and having it inherit the parent file's variable
scope; the script is actually being run on the remote server and the result
is then being included into the local script.
<<<
Try including it as a local file:
require_once library.php'; // if it is in the same directory as the file you
have this line in
Also you don't have to pass $lang via Get to the file as the included code
will have access to $lang as it is then in the scope of the script.
Regards, Torsten
