Merge two array to create an associative array

Question

I have a php array something like this:

array:7 [▼
  "id" => 13
  "agent_id" => 1
  "reserved_by" => 1
  "vehicle_type" => "["Bus","Car"]"
  "no_of_vehicle" => "["2","1"]"
  "created_at" => "2017-06-13 05:46:49"
  "updated_at" => "2017-06-13 05:46:49"
]

Here, vehicle_type and no_of_vehicle are in json_encode format. In the above case,

By json_decode I can get two arrays like this

vehicle_type

dd(json_decode($data->vehicle_type));

array:2 [▼
  0 => "Bus"
  1 => "Car"
]

no_of_vehicle

dd(json_decode($data->no_of_vehicle));

array:2 [▼
  0 => "2"
  1 => "1"
]

Now, what I want is to create an associative array of vehicle type and number equals 1.

array:3 [▼
  Bus => "1"
  Bus => "1"
  Car => "1"
]

It's impossible as all you say because of unique key. But, Is to possible to make similar array with nested like:

array:3 [▼
    array:1 [▼
      Bus => "1"
    ]

    array:1 [▼
      Bus => "1"
    ]

    array:1 [▼
      Bus => "1"
    ]
]

That will be fine for me Any idea, I am using laravel 5.3

Thanks

you wont be able to get your desired array as keys are unique. Why not [Bus=>2,Car=>1] which makes more sense. — Lawrence Cherone

array:3 [▼
  Bus => "1"
  Bus => "1"
  Car => "1"
]

It's impossible, because the keys must unique

you can make it to

["Bus", "Bus", "Car"]

or

["Bus" => 2, "Car" => 1]

Answer to updated question

You can do like this:

$array = [
            "id" => 13,
            "agent_id" => 1,
            "reserved_by" => 1,
            "vehicle_type" => array("Bus", "Car"),
            "no_of_vehicle" => array("2", "1"),
            "created_at" => "2017-06-13 05:46:49",
            "updated_at" => "2017-06-13 05:46:49",
        ];

        $result = [];

        foreach ($array["vehicle_type"] as $key => $vehicle) {
            $num = intval($array["no_of_vehicle"][$key]);
            for ($i = 1; $i <= $num; $i++) {
                $result[] = array($vehicle => "1");
            }
        }

the $result will be:

array:3 [▼
  0 => array:1 [▼
    "Bus" => "1"
  ]
  1 => array:1 [▼
    "Bus" => "1"
  ]
  2 => array:1 [▼
    "Car" => "1"
  ]
]

I would create an array like that :

array[
  {
    vehicle_type => 'Bus',
    no_of_vehicle => 2,
  },
  {
    vehicle_type => 'Car',
    no_of_vehicle => 1,
  }
]

or

array['Bus_1', 'Bus_2', 'Car_1']
