Use this to dynamically register a resource plugin with Smarty. Pass in the name of the resource and the array of PHP functions implementing it. See template resources for more information on how to setup a function for fetching templates.
Technical Note: A resource name must be at least two characters in length. One character resource names will be ignored and used as part of the file path, such as $smarty->display('c:/path/to/index.tpl');
The php-function-array resource_funcs must have 4 or 5 elements.
With 4 elements the elements are the functions-callbacks for the respective source, timestamp, secure and trusted functions of the resource.
With 5 elements the first element has to be an object reference or a class name of the object or class implementing the resource and the 4 following elements have to be the method names implementing source, timestamp, secure and trusted.
