Return an array with AJAX

Hi, I'm new to AJAX

I have un page where i want to call an ajax request to add something on this page.
export.php

<div class="row">
    <div class="span12">
        <select id="listTable" name="listTable">
            <option value="appel">Appels</option>
            <option value="dossier">Dossiers</option>
            <option value="commande">Commandes Fournisseur</option>
         </select>
    </div>
</div>

<div class="row">
    <div class="span12">
         <button class="btn btn-primary" onClick="selectTable()">Select</button>
    </div>
</div>

<div id ="columns" class="row" style="display:none;">
    <div class="span12">
         <div id="columns-check" style="">
            <!-- Here will be displayed the content of the ajax request-->
         </div>
    </div>
</div>

<script type="text/javascript" src="_module/ExportFichier/exportFile/ajax/requestExport.js"></script>

Here is my ajax function

function selectTable(table){

    var table = $("#listTable").val();

        $.ajax({

            url: "_module/ExportFichier/exportFile/ajax/requestColumns.php",
            type: "POST",
            data: "table="+table,
            dataType: 'json',

            success: function(data){

                $('#columns').css('display','block');
                $('#columns-check').empty();

                for(i=0; i<data; i++){
                    $('#columns-check').prepend('<div>I would like to display here the content of my array</div>');
                }
            },

            error: function(){
                alert('The Ajax request did not works!');
            }


        });

}

requestColumns. php

header("content-type: application/json; charset=utf-8");

require_once '../requirements.php';

$tableName = $_POST["table"];

$objService = new ExportFileService($tableName);
$columns = $objService->get_columns();

echo json_encode($columns);

I didn't get the way I can return an array from my requestColumns. php file to my jquery Ajax request and after use it to modify the DOM of my page export.php.
Thanks for your help.

I didn't get the way I can return an array from my requestColumns. php file to my jquery Ajax request

but you’re already returning the array …

use it to modify the DOM of my page export.php.

your array is in the data variable of your success function.
