PHP Code:
temp.message = "Test";
("RC_Tabs").tabecho("Reports", "Report:", temp.message);
RC_Tabs is the database the public function is located at. The first param is the tab name, second param is the name of your echo sorta like "[NPC-Control]:". The last param is the the message you want to be displayed in the tab. Its best to use this method because it works with client-rc on your server into specific tabs.
