php批量上传的实现代码

如下所示：

  if (isset($_post['submit'])) {
   foreach($_files['product_img']['error'] as $k=>$v){
    if ($v == upload_err_ok) {
     $sql ='product_img'.($k+1);
     $tmp_name = $_files['product_img']['tmp_name'][$k];
     $file_name = $_files['product_img']['name'][$k];
     $file_type = $_files['product_img']['type'][$k];
     $upload_name = getpath('../public/upload').time().'_'.$file_name;
     @move_uploaded_file($tmp_name,$upload_name);
     $map[$sql] = $file_name;
     print_r($map);
     exit;
    }
   }
  }
