I have a form submitted with a single input of type of file name: photo[profile][]. I get the this array:

Array
(
[photo] => Array
    (
        [name] => Array
            (
                [profile] => Array
                    (
                        [0] => Chrysanthemum.jpg
                        [1] => Desert.jpg
                    )

            )

        [type] => Array
            (
                [profile] => Array
                    (
                        [0] => image/jpeg
                        [1] => image/jpeg
                    )

            )

        [tmp_name] => Array
            (
                [profile] => Array
                    (
                        [0] => C:\xampp\tmp\php9DCC.tmp
                        [1] => C:\xampp\tmp\php9E0B.tmp
                    )

            )

        [error] => Array
            (
                [profile] => Array
                    (
                        [0] => 0
                        [1] => 0
                    )

            )

        [size] => Array
            (
                [profile] => Array
                    (
                        [0] => 879394
                        [1] => 845941
                    )

            )

    )

)

So, i want a recursive function which will convert my array to this:

Array
(
    [photo] => Array
        (
            [profile] => Array
                (
                    [0] => Array
                    (
                        [name] => Chrysanthemum.jpg
                        [type] => image/jpeg
                        [tmp_name] => C:\xampp\tmp\php9DCC.tmp
                        [error] => 0
                        [size] => 845941
                    )
                   [1] => Array
                    (
                        [name] => Desert.jpg
                        [type] => image/jpeg
                        [tmp_name] => C:\xampp\tmp\php9DCC.tmp
                        [error] => 0
                        [size] => 845941
                    )
            )
    )
)

I need this because i want to upload more photos and set a config for each group of files.

I really tried to make this. I can't figure what so bad in this example. I know that could make a few loops and solve my problem, by this is not really smart and useful... — Dumitru

Nothing wrong with the example. The issue is you are asking US to write all your code for you. SO != Free coders — RiggsFolly

There is no native one, just use a loop.

$result = array();

foreach($_FILES as $key => $value){
   foreach($value as $key2 => $value2){
       foreach($value2 as $key3 => $value3){
           foreach($value3 as $index => $value4){
               $result[$key][$key3][$index][$key2] = $value4;
           }
       }         
   }         
}

The solution using array_column function(available since PHP 5.5) and array_column function:

if (isset($_FILES['photo'])) {
    $quantity = count($_FILES['photo']['size']['profile']);        
    $photos = array_column($_FILES['photo'], 'profile');
    $ordered_list = ['photo' => ['profile' => []]];

    for ($i = 0; $i < $quantity; $i++) {
        $ordered_list['photo']['profile'][] = array_combine(['name', 'type', 'tmp_error', 'error', 'size'], array_column($photos, $i));
    }        
}

Now the $ordered_list contains the needed grouped data
