PHP to return an array to SAJAX, having trouble

I have sajax working, im new to it.

I have a PHP function:

function get_table2_data(){
      return array('achievements', 'second');


then my javascript function that handles the data does this:

function do_table2_update_cb(table_arr) {
      for (j = 0; j < table_arr.length; j++)
              var table2_el = document.getElementById('table2');
              table2_el.options[table2_el.options.length] = new Option(table_arr[j], table_arr[j]);

and that first alert is just showing 'A' as if table_arr is just a string with a value of 'Array'

Any ideas how to get PHP to return a javascript array

try this:

function get_table2_data(){
     return implode(",",array('achievements', 'second'));

function do_table2_update_cb(table_arr) {
     //table_arr is now a csv string
     //now we do an explode after comma
     var arrSplitString=table_arr.split(",");

     for (j = 0; j < arrSplitString.length; j++)
            var table2_el = document.getElementById('table2');
            table2_el.options[table2_el.options.length] = new Option(arrSplitString[j], arrSplitString[j]);

in this way you do not send arrays, you send strings

hope it helped
