For In and Multi Dimensional Arrays

[laurin1]

I've not used for in much in AutoIt, but can For In be used with complex arrays? I am trying to simply iterate through an array like this

$a[0][0] = 'testname'

$a[0][1] = 'testnum'

and AutoIt seems to just ignore it.

If you would iterate through a 2-dim array, it wouldn't be sure in what order you want to iterate through it. You could simulate it though by making a function for reading a 2-dim array into a 1-dim array (for the lines) with 1-dim arrays (the line's contents per line) stored in it's elements, and iterate through the line arrays, line by line, and call that _ForIn2DArray($2dArray,$functionToCallPerElement) or something.

Do you have an example of what's not working for you? Much easier to debug if we can see what your are trying to do.

If you do exactly what he says he does, like the following, you'll see that you don't get a msgbox though you might expect one.

Dim $a[2][2]
$a[0][0]=1
$a[1][0]=2
$a[0][1]=3
$a[1][1]=4

For $x In $a
  MsgBox(0,0,0)
Next

AutoIt just ignores it, like it doesn't exist. In PHP I can write the code either way:

$a[0][0] = 1a

$a[0][1] = 1b

$a[1][0] = 2a

$a[1][1] = 2b

foreach($a as $s){

echo $a[0].$a[1].'<br />';

}

results:

1a1b

2a2b

OR

foreach($a as $s){

foreach($s as $x){

echo $x;

}

echo '<br >';

}

results:

1a1b

2a2b

AutoIt appears to just ignore the for in statement on multi arrays.

Poor mans loop....

Local $a[2][2]
$a[0][0] = '1a'
$a[0][1] = '1b'
$a[1][0] = '2a'
$a[1][1] = '2b'

$string = ""
FOR $i= 0 To UBound($a)-1
    $k = 0
    $string = $string & $a[$i][$k] & @CRLF
    $k +=1
    $string = $string & $a[$i][$k] & @CRLF
NEXT


Msgbox(0,'Test',$string)

not elegant, but may work for you

So the answer to my question is no, AutoIt does not do For In for multi arrays?

as far as i can tell, no it does not work. you have to loop manually to UBound($array). there might be a function for this around allready. good luck.
