copy（）：文件名不能为空-对于某些文件

Question

when I am trying to upload some videos to the server I get this error:

copy(): Filename cannot be empty

I only get this for some videos and not for all of them, but all of them are mp4.

the code is:

$video_name = uniqid().'.'.$extension;
$newname="videos/".$video_name;
$copied = copy($_FILES['video_src']['tmp_name'], $newname);

And both post_max_size and upload_max_filesize are setto 50Mb while the videos are smaller than 10Mb.

Any idea?

Try the move_uploaded_file() function. Also, you should probably change $newname :

$video_name = uniqid().'.'.$extension;
$newname="./videos/".$video_name;
$orig = isset($_FILES['video_src']) && isset($_FILES['video_src']['tmp_name']) ? $_FILES['video_src']['tmp_name'] : '';
if (empty($orig)) {
  echo "Uploaded file doesn't exist.";
}
$copied = move_uploaded_file($orig, $newname);
// Optional
if ($copied) {
  echo "File moved.";
}
else {
  echo "File not moved.";
}
