    Anybody know regex?

    What's a regular expression that will find all occurences of anything between the following characters: {$ and }

    So if I have some text: "The site name is {$site}", I need to match 'site'. It has to be greedy as there may be multiple matches.

    Any ideas? Thanks.

      try using this:

      /\{\$[^\}]+\}/


      BTW:
      "greedy regexp" does not have anything to do with multiple matches...

      if you would use /\{\$.*\}/ on "hello {$site} and a happy new {$what}"

      greedy regexp would match a "{$site} and a happy new {$what}" and the non-greedy one would match a "{$site}" and "{$what}"

          That works perfect, thanks.
