数据表服务器端脚本

Question

我发现这段代码看起来对某些人有用，

$dataArr['aaData'] = Array();
while($row = $res->fetch_assoc()){
$r = Array();
foreach($row as $key=>$value){
    $r[] = "$key $value";
}
$dataArr['aaData'][] = $r;} 
header('Content-Type: application/json');
echo json_encode($dataArr);
/* The output will be of the form, 
{"aaData": [ [
[
   "colname data"
   ...
],
 ] */

但我收到一个错误“ Table id = datos无效的json响应。

我的数据表列与数据库列的名称不同，并且我不确定如何处理。 这是我的js：

   $(document).ready(function() {
function getCpAndVille(data, type, dataToSet) {
return data.cp + " " + data.ville;
}
$('#datos').dataTable({
 "order": [[ 3, "desc" ]],
 "bProcessing": true,
"sAjaxSource": 'ajx/datatable_process_search.php',
"aoColumnDefs": [
                  { "sName": "Réf.", "aTargets": [ 0 ] },
                  { "sName": "Poste", "aTargets": [ 1 ] },
                  { "sName": "Type de contrat", "aTargets": [ 2 ] },
                  { "sName": "Date de publication", "aTargets": [ 3 ]},
                  { "sName": "Lieu", "aTargets": [ 4 ], "mData": getCpAndVille  },
                  { "sName": "Descriptif", "aTargets": [ 5 ] }
                ],

有人可以告诉我应该使用的正确的php代码，因为很难找到它，而且我不理解http://www.datatables.net/examples/data_sources/server_side.html中给出的示例

提前致谢。

控制台网络-> {“ aaData”：[[“ job_id 9261”，“ job_intitule Assistant Achats”，“ job_contrat Int \\ u00e9rim”，“ job_date_insertion 2015-02-20”，“ cp 06110”，“ job_ville 19”]，等等...
