Demonstrates both use of the internal REX variable stack and also use of native PHP variables in REX code.

Dynamic Example

You can dynamically generate REX code (after all it's just PHP code). This example uses PHP to generate some REX code dynamically including a datetime generated by the code server (when it makes the REX file) and then an instruction to get a datetime from the client when the code is executed.

The index.rex file basically exists so you can just call the code without having to specify a particular file (in this case dynamic-rex.php).
