Php json_encode from mysql > output without column names

Question

this is my code on a php page connected to mysql server.

$temp = array();
while($row = mysqli_fetch_assoc($result)) {
    $temp[] = $row;
}
echo json_encode($temp);

The output is:

[{"column1":"1448741941","column2":"951"},{"column1":"1448747281","column2":"862"}]

That's is including the column title + data, and i wanna know how can i get only datas, like

    [[1448741941,951],[1448747281,862]]

Thanks for the help!

Answer 1

Here is the quick answer, send in an array with the data only:

$temp = array();
while($row = mysqli_fetch_assoc($result)) {
    $temp[] = array( $row['column1'], $row['column2'] );
}
echo json_encode($temp);

Edit You might actually whant this too JSON_NUMERIC_CHECK :

$temp = array();
while($row = mysqli_fetch_assoc($result)) {
    $temp[] = array( $row['column1'], $row['column2'] );
}
echo json_encode($temp, JSON_NUMERIC_CHECK);

Another way is this:

    $temp[] = array( 
        intval( $row['column1'] ), 
        intval( $row['column2'] ) );
