Question

我有一个上传文件的脚本。它检查mime类型（应该是音频文件），然后上传它。该类型似乎被识别，但它给出了“无效文件”输出。我错过了一些明显的东西吗？

Upload: songname.mp3
Type: audio/mpeg
Size: 4.5997314453125 MB
Invalid file

脚本的一部分：

if ($_FILES["file"]["error"] > 0)
  {
  echo "Error: " . $_FILES["file"]["error"] . "<br>";
  }
else
  {
  echo "Upload: " . $_FILES["file"]["name"] . "<br>";
  echo "Type: " . $_FILES["file"]["type"] . "<br>";
  echo "Size: " . ($_FILES["file"]["size"] / (1024*1024)) . " MB<br>";
  }
  $allowedExts = array("gif", "jpeg", "jpg", "png");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ((($_FILES["file"]["type"] == "audio/mpeg")
|| ($_FILES["file"]["type"] == "audio/x-mpeg")
|| ($_FILES["file"]["type"] == "audio/mp3")
|| ($_FILES["file"]["type"] == "audio/x-mp3")
|| ($_FILES["file"]["type"] == "audio/mpeg3")
|| ($_FILES["file"]["type"] == "audio/x-mpeg3")
|| ($_FILES["file"]["type"] == "audio/mpg")
|| ($_FILES["file"]["type"] == "audio/x-mpg")
|| ($_FILES["file"]["type"] == "audio/x-mpegaudio")
|| ($_FILES["file"]["type"] == "audio/wav")
|| ($_FILES["file"]["type"] == "audio/x-wav")
|| ($_FILES["file"]["type"] == "audio/ogg"))   
&& ($_FILES["file"]["size"] < 20000000)
&& in_array($extension, $allowedExts))
  {;;
  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
    }
  else
    {//something
    }

    if (file_exists("../sites/default/files/dance/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      }
    else
      {
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "../sites/default/files/dance/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "../sites/default/files/dance/" . $_FILES["file"]["name"];
      }    
  }
else
  {
  echo "Invalid file";
  }

您已经允许这样的扩展程序：

 $allowedExts = array("gif", "jpeg", "jpg", "png");

你至少应该尝试：

 $allowedExts = array("mp3","wav","ogg");

php文件上传 - MIME类型无效？
