Subject: [newbie] How do I match a regex multiple times?

When I use String#match, it only seems to match the regex pattern once. How
do I tell it to match the pattern as many times as possible?

e.g. puts 'robo ruler ruby'.match(/r\w+/)

That only return 'robo', but I would like it to return [robo, ruler, ruby]

I tried using the /g modifier, but Ruby doesn't seem to know about that.

I'm doing this 'cos I'm trying to extract all the function names from a PHP
file, but I shouldn't have to tell it to search it line by line do I?
