How can you make a multidimensional array unique?

Question

I\'ve got a multidimensional array setup like the following:

array(
  [0]=>
  array(
    [\"name\"]=> \"Foo\"
    [\"slug\"]=> \"Bar\"
  )
  [1]=>         


        

Answer 1

function multi_array_unique_by_value($array, $colon = '')
{
    $ret_array = array();
    $has_array = array();
    foreach($array as $item)
    { 
        $item_array = (array)$item;
        if(!in_array($item_array[$colon], $has_array))
        {
            array_push($ret_array, $item);
            array_push($has_array, $item_array[$colon]);
        }
    }
    return $ret_array;
}

You can give your array here and give a colon name for making unique.

On this code, you have multidimensonal array, we foreach that array, which column index for us, we pushing that column values. And when same value, its not adding return array.

So this solution for array_unique for 1 coloumn.
