Merge two array to create an associative array - php

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

Answer 1

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"
]
]

Answer 2

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']
