    An option could be to use a custom filter function like:

        function array_unique_multidimensional(array $array): array {
        
        $sums = [];
        $return_array = [];
        
        foreach($array as $element) {
            $sum = md5(join('', $element));
            if(!in_array($sum, $sums)) {
                $sums[] = $sum;
                $return_array[] = $element;
            }
        }
        
        return $return_array;
    }

    This of course requires that keys in your array elements always come in the same order and that you want to filter uniquely based on all keys.
