PHP多维数组到单个数组

Question

I have a form that allows multiple values for inputs

Car One

<input type="text" name="vehicle[]" placeholder="Enter Your Vehicle" />

Car Two

<input type="text" name="vehicle[]" placeholder="Enter Your Vehicle" />

When submitted it translates to an array like so

["vehicle"]=>
  array(1) {
    [0]=>
    string(5) "Acura"
    [1]=>
    string(5) "Mazda"
 }

["doors"]=>
  array(1) {
    [0]=>
    string(6) "4 Door"
    [1]=>
    string(6) "2 Door"
  }

I want to then translate this to individual arrays that are like so

[VehicleOne]=>
  array(1) {
    [vehicle]=>
    string(5) "Acura"
    [doors]=>
    string(5) "4 door"
  }

I have a custom function I created that does this but I am wondering if there are native php methods that can be used instead of multiple loops?

So this is what I am currently using. Not every $_POST value is an array so I have to check and if is then I divide them up.

foreach ($fields as $key => $row) {

   if(is_array($row)){

     foreach ($row as $column => $value) {

        $doctors[$column][$key] = $value;

     }

  }

}

No need, just construct the array the way you want it in the inputs:

<input type="text" name="data[0][vehicle]" placeholder="Enter Your Vehicle" />
<input type="text" name="data[1][vehicle]" placeholder="Enter Your Vehicle" />
<input type="text" name="data[0][doors]"   placeholder="Enter Your Doors" />
<input type="text" name="data[1][doors]"   placeholder="Enter Your Doors" />

Then $_POST will contain:

Array
(
    [data] => Array
        (
            [0] => Array
                (
                    [vehicle] => Acura
                    [doors] => 4 door
                )

            [1] => Array
                (
                    [vehicle] => Maza
                    [doors] => 2 door
                )
        )
)

If you can't/won't change the form, then something like:

foreach($_POST['vehicle'] as $k => $v) {
    $result[] = ['vehicle' => $v, 'doors' => $_POST['doors'][$k]];
}

Will yield:

Array
(
    [0] => Array
        (
            [vehicle] => Acura
            [doors] => 4 door
        )

    [1] => Array
        (
            [vehicle] => Maza
            [doors] => 2 door
        )
)

Using something like VehicleOne etc. is pointless when using arrays as you are only doing this to make it unique, when 0, 1, etc. already is.
