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.

Have you actually tried anything before asking others to write the code for you? — Aleks G, Jul 21 '14 at 11:05

I voted duplicate, but wanted to indicate: I understand you can't find that solution. Don't see the duplicate as a punishment :) — Martijn, Jul 21 '14 at 11:07
it is not duplicate.in this case the inner arrays contain different values so those solutions will not work for this. — Sougata Bose, Jul 21 '14 at 11:49

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;
    }
}
