I know this should be fairly basic so I must be doing something wrong.

I'm sending a json_encoded string from my php file to C2. The string shows [4,3,1,3,1,2,1,1,0,3] when C2 receives it (when set in a text object). It's just 10 numbers in PHP.

I then try to load it into my C2 array with Array -> Load from JSON string (String).

The array is still empty, so I'm doing something wrong. Any ideas?

Make sure your ecapsulating the php array in the format that the C2 array is expecting.

 $myArray = array();
    $myArray[] = 4;
    $myArray[] = 3;
    $myArray[] = 1;
    $myArray[] = 3;
    $myArray[] = 1;

    $output = array(
	'c2array' => true,
	'size' => array(
	    0 => count($myArray),
	    1 => 1,
	    2 => 1
	),
	'data' => array()
    );

    $x = 0;
    foreach ($myArray as $value) {
	$output['data'][$x] = array();
	$output['data'][$x][0] = array();
	$output['data'][$x][0][0] = $value;
	$x++;
    }

    return json_encode($output);
[/code:1gjt5210]

The resulting JSON string would look like this :
{"c2array":true,"size":[5,1,1],"data":[[[4]],[[3]],[[1]],[[3]],[[1]]]}

You can now take this string as is and load to the Array in C2
