Message: [QUOTE="Jeroen Heijmans, post: 4508550"] Hi, I'm looking for a function that can do the same thing as the strtr function in PHP (and possibly other languages, I don't know). That is, I would like to replace multiple parts of a strings simultaneously, so that you can (among others) swap strings: strtr("AA BB", array("AA" => "BB", "BB" => "AA")); // "BB AA" I've been trying to find a Ruby equivalent, but haven't so far. The tr functions in String only deal with single characters, and replace or gsub only deal with one replacement at a time. Any functions that I missed, or perhaps a library with this functionality available? thanks, Jeroen Heijmans [/QUOTE]
