478055 PHP Data Display and Editing

Hi! I need a PHP based web interface for reading, displaying, allowing editing, and saving configuration data stored on an XML file. It should work like this: User logs in (password protection). The script reads in data from an XML file on the server. There are a few pages of data, so it has o be split into a number of pages which display static text showing the name of the configuration variable, and the variable read from the file. The user should be able to edit the variables. Types of variables include numeric, string, and choice of fixed strings ( eg low, medium, high ) The data should be checked for validity. There should be navigation buttons to allow switching to the different data entry pages. On the main page there should be user interface to Open configuration files of different names, Save, and Save As. There should also be a button for setting default, shich would save the settings to a file named default_settings.xml. There are about 250 variables This web based configuration system is replacing a windows based program that is available as a reference. Layout of new system can copy the layout of existing system.
