Never encountered this error, no matter if I would run that in shell or
through the web server.

You could try

if (array_key_exists('username',$_REQUEST)) {
$username=$_REQUEST['username'];
}

This would first check the $_REQUEST array and see if there is key called
"username" before trying to assign the value to the variable $username.

If you still get an error message, but the script seems to work as it should,
then do

if (@array_key_exists('username',$_REQUEST)) {
$username=$_REQUEST['username'];
}

notice the '@' in front of array_key_exists(), it's there to suppress error
messages.

Don't forget to access the page with the url

http://your.host.net/~yourusername/index.php?username=yourusername


Usually you try to fetch the variables as early as possible in the script and
don't do that inside a function, as this usually can mess things up as there
is the possibility that you get a function-local array instead of the global one.
