   3  * PHP lacks an interactive mode, but this can be very helpful when debugging.
   4  * This script lets a command-line user start up the wiki engine and then poke
   5  * about by issuing PHP commands directly.
   6  *
   7  * Unlike eg Python, you need to use a 'return' statement explicitly for the
   8  * interactive shell to print out the value of the expression. Multiple lines
   9  * are evaluated separately, so blocks need to be input without a line break.
  10  * Fatal errors such as use of undeclared functions can kill the shell.
  11  *
  12  * To get decent line editing behavior, you should compile PHP with support
  13  * for GNU readline (pass --with-readline to configure).
