Thank you all it will work for me.

    $room_type_id = (array) $request->input("room_type"); //multiple value
    $block_name = (array) $request->input("block_name"); //multiple value

    $array = [];
    foreach($room_type_id as $key => $room)
        foreach($block_name as $k => $block)
            if($key == $k)
                foreach(explode(',', $block) as $b)
                    $array[] = ['room' => $room,'block'=>$b];
    
    echo '<pre>';
    print_r($array);

Array(
[0] => Array
    (
        [room] => 8
        [block] => A
    )

[1] => Array
    (
        [room] => 8
        [block] => B
    )

[2] => Array
    (
        [room] => 8
        [block] => C
    )

[3] => Array
    (
        [room] => 9
        [block] => X
    )

[4] => Array
    (
        [room] => 9
        [block] => Y
    )

[5] => Array
    (
        [room] => 9
        [block] => Z
    )

)
