Answer 1

Use json_encode() function and echo it in javascript

    while ($rows = pg_fetch_array($qry))
    {
        ?>
        <option  value="<?php echo $rows['relation_name_local']?>">
        <?php echo $rows['relation_name_local']?>
        </option>
        <?php
        $app_relation_array[] =  $rows['relation_name_local'];
        $new_data = json_encode($app_relation_array[]);
    }?>

And in your html inside script tag

     <script>
        var data = JSON.parse("<?php echo $new_data; ?>");
        alert(data);
     </script>
