How to pass PHP 2d array to JS script?

Question

Let's say I have a table

[table fruits]
--------+------------+
ID [PK] | fruit      |
--------+------------+
1       | Orange     |
2       | Banana     |
3       | Coconut    |

and I need to save a list of IDs and names in a JS array, like for example:

var fkOptionList = [[1]['Orange'],[2]['Banana'],[3]['Coconut']]

in PHP I achieved this by:

        $fkOptionTableR = $fkOptionTableQ->result_array();

        $fkOption2dArray[] = array();
        $i = 0;
        $j = 0;

        foreach ($fkOptionTableR as $array) {
          foreach ($array as $row) {
          $fkOption2dArray[$i][$j] = $row;
            $j++;
          }
          $i++;
          $j = 0;
        }

which results in (according to var_dump):

array(3) { 
[0]=> array(2) { [0]=> string(1) "1" [1]=> string(6) "Orange" } 
[1]=> array(2) { [0]=> string(1) "2" [1]=> string(6) "Banana" } 
[2]=> array(2) { [0]=> string(1) "3" [1]=> string(7) "Coconut" } 
}

I would need that array in my JS script, but the problem is it's in other file (above PHP script is loaded once by a CI's controller). Is there a way to pass it?

@RocketHazmat - right, it meant to be fkOptionList = [[1, 'Orange'],[2, 'Banana'],[3, 'Coconut']] — van_folmert

In PHP

$yourArray = json_encode($fkOptionTableR);

In JAVASCRIPT

var twoDarray = <?php echo $yourArray ?>

the second doesn't work (unexpected <), anyway I have my json_encoded array in a div, but don't know how can I paste its content to a JS variable body so that it will become an array?

use var array = $("#That Div Id").text();

I've tried, it treats var array like a string then, not as an array

when I use alert(fkOptionList[1]); it returns [ instead of array's element

I've made a workaround, creating JS var in PHP script, instead of echoing it in a div. Thanks for help.
