Jquery DataTable Error when rendering php Array to Client

Question

I have sent data json_encoded from a PHP Page:

$arrayForDataTablePopulation = array();

        while (($row = oci_fetch_array($stid, OCI_BOTH)) != false) {

                $a = trim($row["IDCONF"]);
                $b = trim($row["NOME"]);
                $c = trim($row["TIPOLOGIA"]);
                $d = trim($row["STATO"]);
                $e = trim($row["AMBIENTE"]);
                $f = trim($row["AGGREGATORE"]);
                $f2 = trim($row["NOMECED"]);
                $g = trim($row["MODELLO"]);
                $h = trim($row["CONTRATTO"]);
                $i = trim($row["VALIDADAL"]);
                $l = trim($row["VALIDAAL"]);

            if ($count < $NUM){

                $arrayForDataTablePopulation[$count] = "[" .  $a . "," .  $b . "," . $c . "," . $d . "," . $e . "," . $f . "," . $f2 . "," . $g . "," . $h . "," . $i . "," . $l . " ]";
                $count++;

            } else {

                $arrayForDataTablePopulation[$count] = "[" .  $a . "," .  $b . "," . $c . "," . $d . "," . $e . "," . $f . "," . $f2 . "," . $g . "," . $h . "," . $i . "," . $l . " ]";

            }

        }

        echo  json_encode($arrayForDataTablePopulation);

} else {

    echo "No data Received. Dimensione array: " . $receivedArrayFormSize;

}

I don't know why my ouput is bad rendered:

I think I have bad encoded the array from the server. The Ajax side is:

$.ajax({

                url: "asset_GestAsset.php",
                type: "POST",
                data: { "fieldValue" : JSON.stringify(arrForm) },
                success: function(data) {

                    var tableData = JSON.parse(data);

                    console.log(" Converti in stringhe: " + data.toString() + " !!! Everything ok");

                    $('#OUTCOME_RESEARCH_TABLE').DataTable({
                         "aaData":tableData,
                         "deferLoading": 57,
                         "deferRender": true,
                         "scrollY": 150,
                         "iDisplayLength": 100,
                         "scrollX": true,
                         "bRetrieve": true,
                         "bDestroy": true,
                         "ordering": false,
                         "info":     true,
                         "sDom":     'ltipr',
                         "bDestroy": true

                 });

etc...

The problem is I am confused with all this Array/JSON stuff I think I have a lot of confusion in my mind right now xD Someone could please help me to find out a workaround to solve this problem? Is the PHP side wrong or the code in the AJAX?

What I would like to do is to modify the server array, send back to the client and render the DataTable properly.

PHP

You should use the code below to populate the array:

$arrayForDataTablePopulation[$count] = array($a, $b, $c, $d, $e, $f, $f2, $g, $h, $i, $l);

To print the JSON use the code below:

header('Content-type: application/json');
echo json_encode($arrayForDataTablePopulation);

JS

Use the code below inside success handler:

$('#OUTCOME_RESEARCH_TABLE').DataTable({
     "dom": 'ltipr',
     "data": data,
     "pageLength": 100,
     "scrollY": 150,
     "scrollX": true,
     "ordering": false
});
