I am trying to upload a doc file from a form and send it to email. I am using

问题是，它正在返回随机生成的文件名.因此，到达收件箱时，文件名是phpvwRGKN.dat(每次文件名都是随机的).

The problem is, it is returning a randomly generated file name. So, when it reaches the inbox, the filename is phpvwRGKN.dat (filename is random each time).

注意:我正在使用推荐答案

$_FILES['file']['tmp_name'];将包含服务器上文件的临时文件名.在您处理文件之前，这只是服务器上的占位符

$_FILES['file']['tmp_name']; will contain the temporary file name of the file on the server. This is just a placeholder on your server until you process the file

$_FILES['file']['name'];包含从用户计算机上传的文件的原始名称.

$_FILES['file']['name']; contains the original name of the uploaded file from the user's computer.
