如何使用ajax从mysql查询向jquery表添加行?

I need insert rows into a jQuery DataTable from AJAX. In AJAX I call a PHP file when I make a query to my mySql database, but I get show only a character in rows. It is because the format returned is incorrect, but I can't to parse the correct format.

$query = "..myquery..";
if ($row = mysql_fetch_array($sql)) {
    do {
        $arr []= $row['name'];
    } while ($row = mysql_fetch_array($sql));
    echo json_encode($arr); // Here I tried return array without json_encode and a lot of things...
}

I know that the format to add the rows with .DataTable().row.add() is the below, but I do not get the desired format.

[["Element software"], ["Software dist"],["Global envir"], ["Software"], ["Software list"]] 

How can I get this format in the echo to returned this?? Thanks!

    It is array of arrays, so you need to push an array to $arr, not a string:

    $query = "..myquery..";
    $arr = []; // init an empty array
    // no need to do if() and do{}while() inside. You can just while(){} it
    while($row = mysql_fetch_array($sql)){ 
        $arr[]= [$row['name']]; // <== these square brackets do the trick  
    }
    echo json_encode($arr); // still need to json_encode
