"in" operator on returned array.

The error I've found is that if you want to use the var in array, the array needs to be a variable defined in the function itself; not a returned value from a function. ( I also highly suspect that someArray()[2] doesn't work. )

PHP Code:


		
			
function someArray() {

  return {0,1,2,3};

}



function onCreated() {

  if ( 2 in someArray() ) {

    echo("Works!");

  } else {

    echo("Doesn't work.");

  }

}

I've also noticed this. I tried something along these lines not so long ago and I had to migrate the array to the function it was being used in or it would not work at all, which is really quite annoying, inconvenient and can be generally unclean if you want to group some different arrays in a single function to avoid having them scattered throughout the different functions they're used for.

I've also noticed this. However, someArray()[2] will work.

May be you need to do "var in (someArray())" or so, the in-operator accepts several different formats so it might stumble if you just do "in func()"

var in {someArray()}?

No, ( ) instead of { }, although I bet both works.

Well I said {} because that typically forces something into an array, right? Though I suspect this will also turn it into a subarray in an array... which will make it equally unusable. Just throwing the idea out there, though.

edit: I just copied and pasted your script, Novo, and it worked fine for me... at least on the serverside.

Works!

edit2: works on the clientside too...

Hmmm I remember there was some bug in older versions of the npcserver and clients where functions couldn't correctly return arrays.

Ah. Alright. I had the problem on a Mac Intel version... I might have an outdated copy.
