From the above input arrays, how to remove the duplicate array values, I mean 'Moto G' and 'Nokia' products are duplicate. So please give the solution for changing the input formats to output formats.

I voted duplicate, but wanted to indicate: I understand you can't find that solution. Don't see the duplicate as a punishment :) — Martijn

it is not duplicate.in this case the inner arrays contain different values so those solutions will not work for this. — Sougata Bose

try this

$new_array = array();
$temp_array = array();
for($your_array as $key=>$arr_val)
{
    $arr = array();
    foreach($arr_val as $val)
    {
        if(!in_array($val, $temp_array))
        {
            $arr[] = $val;
            $temp_array[] = $val;
        }
    }

    if(sizeof($arr)>0)
    {
        $new_array[$key] = $arr;
    }
}
