Perhaps it'd be better to use a style such as --username=bob and parse everything from -- to the equal sign as the key and everything afterword as the value. > > If you want the user to be able to enter a value, try using fgets on stdin (See the > > fopen() docs for > > instructions on how to open stdin, stdout, or stderr). It should be somewhat like this: > > > > $stdout = fopen("php:// stdout"); > > $stdin = fopen("php://stdin"); > > > > fputs($stdout, "Username: "); > > fgets($stdin, $Username); > > > > I really really need to sit down sometime and read EVERY page of that > manual :) One thing I've been wishing is that there was some exposed versioning system in the manual code. It'd be really cool to be able to see what's new in recent versions in a form a little friendlier than diff php3_manual_file.html php4_manual_file.html.
