Looking to bullet-proof

[s_shrum]

I wrote this in like 3 hours with no knowledge of the 12-or-so functions that I used. It works, but will choke if various things are not in place.

Looking to bullet-proof it and maybe even tighten it up.

for those massive echo statements you might try heredoc syntax (types.string at php.net). also, if you're running this through the CLI (as you should be) just use $argc and $argv, they're automatically registered as global by default in the CLI.
