in reply to Converting a hash element into an array

I wrote the following in JavaScript a few years ago. The logic should be the same in Perl, but I'll leave porting it as an exercise for the reader.
var query_string = {}; var query =; var vars = query.split("&"); for (var i=0;i<vars.length;i++) { var pair = vars[i].split("="); // If first entry with this name if (typeof query_string[pair[0]] === "undefined") { query_string[pair[0]] = pair[1]; // If second entry with this name } else if (typeof query_string[pair[0]] === "string") { var arr = [ query_string[pair[0]], pair[1] ]; query_string[pair[0]] = arr; // If third or later entry with this name } else { query_string[pair[0]].push(pair[1]); } }
