Using the 'in' operator with multi dimensional arrays

Hi all, I am working on an events system and want to use multi dimensional arrays but that standard "in" operator doesn't work like that, how else would I be able to check if the event name is correct?

PHP Code:


		
			
temp.array = {
    {
        "test", "30", "30"
    }, {
        "event", "30", "30"
    }
};
if (eventName in temp.array) {}

Probably easiest to just maintain a separate array with only event names. Or cycle through the array you have and check against the name against the first param of each.

Yeah well if there wasn't a simple way to do that then I think it's best to have an array the names, /thread

If you want to keep them in the same array do something like this:

PHP Code:


		
			
temp.events = {

  "event", {30, 30, "otherdata"},

  "event2", {20, 20, "loldata"}

};



temp.event_name = "event";

temp.event_index = temp.events.index(temp.event_name);

if (temp.event_index >= 0) {

  temp.event_data = temp.events[temp.event_index+1];

  // do stuff

}

The in operator will also work as well in this case.
