My aim to create multiple possible of out comes with 3 arrays.

I achieved it but i got struck with one problem.

I find there is repeated values with different keys.

below is the code i tried to generate .

$top = array(array('toplinner_name' => M1), array('toplinner_name' => M2));
$flute1 = array(array('f1_name' => M3));
$single_array = compares($top, $flute1); //combaining arrays
$bottom = array(array('bottomlinner_name' => M1), array('bottomlinner_name' => M2));
$single_array = compares($single_array, $bottom); //combaining arrays

function compares($a, $b) {
    if (is_array($a) && is_array($b)) {
        if (count($a) < count($b)) {
            list($a, $b) = array($b, $a);
        }
        $new = array();
        $k = 0;
        for ($i = 0; $i < count($b); $i++) {
            for ($j = 0; $j < count($a); $j++) {
                $new[$k] = array_merge($b[$i], $a[$j]);
                $k++;
            }
        }
        return $new;
    }
    return null;
}

with the above code i am getting out put as

Array{
     '0'=>{'toplinner_name'=>'M1','f1_name'=>'M3','bottomlinner_name'=>'M1'},
     '2'=>{'toplinner_name'=>'M1','f1_name'=>'M3','bottomlinner_name'=>'M2'},
     '3'=>{'toplinner_name'=>'M2','f1_name'=>'M3','bottomlinner_name'=>'M1'},
     '4'=>{'toplinner_name'=>'M2','f1_name'=>'M3','bottomlinner_name'=>'M2'},
  }

As you can see from the above out put 2 and 3 are same linners so i need t0 consider them as one how can i remove those duplicate values..... i tried below code

$input = array_map("unserialize", array_unique(array_map("serialize", $new)));

but it gives me same out put.

my desired out put should be

Array{
     '0'=>{'toplinner_name'=>'M1','f1_name'=>'M3','bottomlinner_name'=>'M1'},
     '1'=>{'toplinner_name'=>'M1','f1_name'=>'M3','bottomlinner_name'=>'M2'},
     '2'=>{'toplinner_name'=>'M2','f1_name'=>'M3','bottomlinner_name'=>'M2'},
  }
