在php中触摸上传的文件

Question

I would like to change the modification time of an uploaded file because it always returns 01 January 1970, so I am doing the following:

if (move_uploaded_file($_FILES["file"]["tmp_name"], $target_file)) {
        touch($_FILES["file"]);
        header ('Location: http://www.example.com/php/manager');
        // file uploaded but filemtime is 01 Jan 1970
}

Answer 1

you're passing the array to touch() !! You need to pass $_FILES['file']['tmp_name'] - a string. Actually though, you need to touch $target_file since that's the final destination; after moving, $_FILES will no longer be there to touch

I will be the first to admit this is not a solution to WHY your dates are not preserving, and I will follow this thread, but to what you're wanting to accomplish, this is the answer.
