Look at the methods String and Regexp provide.
Like String#match, Regexp#match, String#=~, Regexp#=~, String#scan,
String#sub, String#gsub.
Also take a look at MatchData (returned by the #match methods).
For case insensitivity, use the i switch, example: /foo/i, or %r{foo}i
(/regex/ is a regex literal which does the same as Regexp.new('regex'),
%r{regex} is just a different way to write it).

Regards
Stefan

Hi,

Of course :

I don't know PHP but I think match is the closer equivalent of ereg

re.match(string) or string.match(re) => object matchdata

This object matchdata has methods like pre_match and post_match.
