input[type='file']을 여러 개 업로드하는 방법은 무엇입니까?

<input name="upload[]" type="file" multiple="multiple" />

// Count # of uploaded files in array
$total = count($_FILES['upload']['name']);

// Loop through each file
for($i=0; $i<$total; $i++) {
  //Get the temp file path
  $tmpFilePath = $_FILES[&#39;upload&#39;][&#39;tmp_name&#39;][$i];

  //Make sure we have a filepath
  if ($tmpFilePath != ""){
    //Setup our new file path
    $newFilePath = "./uploadFiles/" . $_FILES[&#39;upload&#39;][&#39;name&#39;][$i];

    //Upload the file into the temp dir
    if(move_uploaded_file($tmpFilePath, $newFilePath)) {

      //Handle other code here

    }
  }
