现在处理文件上传量的文件是以下

?php session_start();

ini_set('memory_limit', "400M");
ini_set('max_execution_time', "900");
ini_set('upload_max_filesize', "400M");
ini_set('post_max_size', "400M");



$user=$_SESSION['MM_Username'];

$path="video". "\\" . $user . "\\";

if(!(is_dir($path))){
mkdir(dirname(__FILE__) . "\\". $path,0777);
}

  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    }
  else
    {
    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
    echo "Type: " . $_FILES["file"]["type"] . "<br />";
    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
    echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";

    if (file_exists($path . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      $path. $_FILES["file"]["name"]);
      echo "Stored !";
      }
    }

?>

如果我尝试上传一张图片一切都很好，但是当我尝试上传一个300MB的动画片段它会给出我上面发布的错误，我已经更改了我的wamp服务器上的php.ini文件，它允许更大的文件到上传但仍无结果有人知道什么是错的吗？

Answer 1

您缺少表单上的enctype属性。

Answer 2

您的代码中的另一个问题是您甚至不检查$ _FILES []数组中是否存在'file'索引。如果没有，则应将此报告为错误，而不是尝试使用其内容。这是更好的整体方法：在尝试使用表单之前，检查您希望表单中的每个字段是否存在。
