Question

My php side

   $i = 1;
   while ($row = mysql_fetch_array($query)) {
       $productarray[$i][] = $row['product_id'];
       $productarray[$i][] = $row['product_model'];
       $productarray[$i][] = $row['product_type'];
       $productarray[$i][] = $row['product_return'];
       $i++;
    }
    $jsonstring = json_encode($productarray);

This is what im getting Is this a valid json string

{
 "1":["1","HFJ5G1.5","plat","graviteits"],
 "2":["2","HHJ5S2.5","holle plunjer","veer"],
 "3":["3","HTJ5S7.5","inbouw","veer"]
}

i cant iterate through this someone please tell me how to iterate this json

From the json site i think this is the format if so how can i change the above json string to this format ?

{
 "1":[{"1","HFJ5G1.5","plat","graviteits"}],
 "2":[{"2","HHJ5S2.5","holle plunjer","veer"}],
 "3":[{"3","HTJ5S7.5","inbouw","veer"}]
}

You need to refactor your PHP code a tad bit. Try doing something like this:

$productarray = array();
while ($product = mysql_fetch_assoc($query)) { // NOTE: using associative array
    $productarray[] = $product;
}
echo json_encode($productarray);

// Output
// [{
//     "product_id": "1",
//     "product_model": "HFJ5G1.5",
//     "product_type": "plat",
//     "product_rturn": "graviteits"
// }, {
//     "product_id": "2",
//     "product_model": "HHJ5S2.5",
//     "product_type": "holle plunjer",
//     "product_rturn": "veer"
// }, {
//     "product_id": "3",
//     "product_model": "HTJ5S7.5",
//     "product_type": "inbouw",
//     "product_rturn": "veer"
// }]

Notice that it now becomes very easy to iterate. You can do so as follows:

var o = [{
    "product_id": "1",
    "product_model": "HFJ5G1.5",
    "product_type": "plat",
    "product_rturn": "graviteits"
}, {
    "product_id": "2",
    "product_model": "HHJ5S2.5",
    "product_type": "holle plunjer",
    "product_rturn": "veer"
}, {
    "product_id": "3",
    "product_model": "HTJ5S7.5",
    "product_type": "inbouw",
    "product_rturn": "veer"
}];
for (var i = 0; i < o.length; i++) {
    console.log("Product " + (i + 1) + " has model:" + o[i]["product_model"]);
    console.log("Product " + (i + 1) + " has type:" + o[i]["product_type"]);
}
