Detailed Description

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).
