如何遍历$ _FILES数组的多维数组

Question

I am using dropzone to get the files uploaded to my Folder. Successfully getting the array of files.

   foreach($_FILES as $file) {
       print_r($file);
    }

Current Output:

Array
(
    [name] => Array
        (
            [0] => Image.PNG
            [1] => sadssadsa.PNG
        )

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

    [tmp_name] => Array
        (
            [0] => C:\Users\CH MANAN\AppData\Local\Temp\php48B6.tmp
            [1] => C:\Users\CH MANAN\AppData\Local\Temp\php48B7.tmp
        )

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

    [size] => Array
        (
            [0] => 291647
            [1] => 112790
        )
)

Expected output:

array
(
    [0] => array
    (
        [name] => Image.PNG
        [type] => image/png
        [tmp_name] => C:\Users\CH MANAN\AppData\Local\Temp\php48B6.tmp
        [error] => 0
        [size] => 291647
    )

    [1] => array
    (
        [name] => sadssadsa.PNG
        [type] => image/png
        [tmp_name] => C:\Users\CH MANAN\AppData\Local\Temp\php48B7.tmp
        [error] => 0
        [size] => 112790
    )
)

Tried various loops in the parent loop but not getting the expected results. Someone can help here.

You can use this:

$keys = array_keys($_FILES); // get all the fields name
$res = array_map(null, ...array_values($_FILES)); // group the array by each file
$res = array_map(function ($e) use ($keys) {return array_combine($keys, $e);}, $res); // insert the field name to result array

array-keys, array-map and array-combine
