[SOLVED] Multidimensional array: bug? or I'm misusing?

Well, here's the PoC:

#include 'array.au3'
$test = "ab-cd+ef"
$test = StringSplit($test, "+") ; we will have ["ab-cd", "ef"]
_ArrayDisplay($test) ; confirm it
$test[1] = stringsplit($test[1], "-") ; we will have [ [ "ab", "cd" ], "ef" ]
_ArrayDisplay($test) ; confirming it
_ArrayDisplay($test[1]) ; confirming the [ "ab", "cd" ]

; This works:
msgbox(0, "", ( $test[1] )[1] ) ; we get "ab"

; But this doesn't:
msgbox(0, "", $test[1][1]) ; we get an error

#cs
Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
msgbox(0, "", $test[$i][1])
msgbox(0, "", ^ ERROR
#ce

Is this a bug or this is really how AU3 works?

Running AutoIt 3.3.14.2 on Win7 x64 (running the x86 version of AU3).

Running AutoIt 3.3.14.2 on Win7 x64 (running the x86 version of AU3).

You're not creating a multidimensional array here, you're creating an array of array(s).  

 

Your first line of code works because Au3 interprets it as:  "Look at $test[1], and then give me the value in the second index of that array".  The second doesn't work, because its saying "give me the second row, second column in array $test"  which of course, doesn't exist.

 

You would initialize a multi-dimensional array like this:

 

 

local $test[2][2] = [["ab","cd"],["ef","hg"]]

msgbox(0,'',$test[1][1])

There would be no way to add a stringsplit into a multi-d array with standard UDF's.. you'd have to loop through it and addyourself.

In a word, yes, it's syntax.  The failing notation is for 2 dimensional arrays, as kaisies mentioned.

Okay, I think I've played too much with PHP where arrays are just like modeling clay LOL

Thanks for the info guys! :)
