Spiff this up a bit:

Browse source 
* output data returned by the eval; prints strings and numbers directly, var_dump()s arrays and objects
* if no returned data, print a line break. This makes things easier when doing 'echo' and you forget to add one yourself.
* Add some documentation comments

<?php
/**
* @todo document
* PHP lacks an interactive mode, but this can be very helpful when debugging.
* This script lets a command-line user start up the wiki engine and then poke
* about by issuing PHP commands directly.
*
* Unlike eg Python, you need to use a 'return' statement explicitly for the
* interactive shell to print out the value of the expression. Multiple lines
* are evaluated separately, so blocks need to be input without a line break.
* Fatal errors such as use of undeclared functions can kill the shell.
*
* To get decent line editing behavior, you should compile PHP with support
* for GNU readline (pass --with-readline to configure).
