HTML:

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

PHP:

// 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 = $_FILES['upload']['tmp_name'][$i];

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

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

      //Handle other code here

    }
  }
}

var_dump($_FLIE);
把变量打印出来看看结构就知道怎么接受了
