These are code examples for REX and are hosted on the PurplePixie server.
For each one you can request the URL from REX and it will execute or view the code online.
Hello World Example
The simplest REX example - just writes 'Hello World!' via a PHP echo statement.
REX URL: http://rex.purplepixie.org/examples/hello-world/for example: php rex.php http://rex.purplepixie.org/examples/hello-world/
Code View URL: http://rex.purplepixie.org/examples/hello-world/
Shows an incrementing counter through repeated calls to the same script.
Demonstrates both use of the internal REX variable stack and also use of native PHP variables in REX code.

You can dynamically generate REX code (after all it's just PHP code). This example uses PHP to

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
