PHP上传某些文件类型,“invalid filetype”?

所以我正在尝试将上传功能添加到只允许某些文件类型的联系页面。这些文件应存储在“upload”文件夹的根目录中。但是,文件没有上传,我在PDF和docx文件上收到“无效文件”错误(如编程),但无法弄清楚原因。任何人都可以提供任何见解吗?

<?php

    if($_POST) {

      if($_POST["token"]==true){
        $allowedExts = array("pdf","docx", "doc");
        $temp = explode(".", $_FILES["file"]["name"]);
        $extension = end($temp);
        if ((($_FILES["file"]["type"] == "application/pdf")
        || ($_FILES["file"]["type"] == "application/docx")
        || ($_FILES["file"]["type"] == "application/doc"))
        && ($_FILES["file"]["size"] < 20000)
        && in_array($extension, $allowedExts))
          {
          if ($_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"] / 6144) . " kB<br>";
            echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";

            if (file_exists("upload/" . $_FILES["file"]["name"]))
              {
              echo $_FILES["file"]["name"] . " already exists. ";
              }
            else
              {
              move_uploaded_file($_FILES["file"]["tmp_name"],"upload/" . rand().$extension);
              echo "Stored in: " . "upload/" . "rand().$extension)";
              }
            }
          }
        else
          {
          echo "Invalid file";
          }
?>

docx文件的文件类型不是application/docx而是application/vnd.openxmlformats-officedocument.wordprocessingml.document,但您也可能将其视为application/zip; doc文件的mime类型为application/msword ,而不是application/doc
