One of our readers just wrote a new PHP command line utility that makes it VERY easy to get up and running with testing your PHP scripts. You can check out what he has done at http://www.travistidwell.com/node/86
He also included an easy-to-use method for compiling your PHP scripts as stand-alone executables.
The utility is a free download. All he is asking is that you let him know what you think and if it was helpful.
