HTML PHP 表单仅上传 .doc 和 .docx [关闭]

Question

我需要一些语法方面的帮助。我需要上传 .doc 或 .docx 文件的可能性。但我不知道该怎么做。请看我的代码：

//Сheck that we have a file
if((!empty($_FILES["datafile"])) && ($_FILES['datafile']['error'] == 0)) {
  //Check if the file is JPEG image and it's size is less than 2mb
  $filename = basename($_FILES['datafile']['name']);
  $ext = substr($filename, strrpos($filename, '.') + 1);
  if (($ext == "docx,doc") && ($_FILES["datafile"]["type"] == "application/vnd.openxmlformats-officedocument.wordprocessingml.document") && 
    ($_FILES["datafile"]["size"] < 2100000)) {
    //Determine the path to which we want to save this file
      $newname = dirname(__FILE__).'/upload/'.$filename;
      //Check if the file with the same name is already exists on the server
      if (!file_exists($newname)) {
        //Attempt to move the uploaded file to it's new place
        if ((move_uploaded_file($_FILES['datafile']['tmp_name'],$newname))) {
           $sasquach = "The file has been saved as: ".$newname;
           $link= 'http://orchardsystems2012.co.za/'.$_SERVER['PATH_INFO'].'/upload/'.$filename;
        } else {
           //echo "Error: A problem occurred during file upload!";
        }
      } else {
         //echo "Error: File ".$_FILES["datafile"]["name"]." already exists";
      }
  } else {
     //echo "Error: Only .jpg images under 2mb are accepted for upload";
  }
} else {
 //echo "Error: No file uploaded";
}

请帮忙:)

      && (in_array($_FILES["datafile"]["type"], array("application/msword", "application/vnd.openxmlformats-officedocument.wordprocessingml.document"))
