You can simply use array_map for this, to wrap each element into another array:

$data['fileToUpload'] = array_map(
  function($item) {
    return [$item];
  },
  $data['fileToUpload']
);

Easy enough to build a new array:

$array = [
    'fileToUpload' => [
        'name' => 'KERINOX COFFEE.jpg',
        'type' => 'image/jpeg',
        'tmp_name' => '/opt/lampp/temp/phpuk5Uyo',
        'error' => 0,
        'size' => 2440617
    ]
];
$newArray = ['fileToUpload' => []];

foreach ($array['fileToUpload'] as $key => $value)
    $newArray['fileToUpload'][$key][] = $value;

 $myArray = [];
 $myArray['fileToUpload']['name'] = array("file name");
 $myArray['fileToUpload']['type'] = array("file type");
 $myArray['fileToUpload']['tmp_name'] = array("temporary name");
 $myArray['fileToUpload']['error'] = array("error");
 $myArray['fileToUpload']['size'] = array("file size");

 echo "<pre>";
 print_r($myArray);
