Answer 1

目标文件夹可能没有写入权限

Answer 2

foreach ($_FILES['atc']['tmp_name'] as $key => $tmp_name){
$path = "home/goes/attachments/" . $fileName";
move_uploaded_file($tmp_name, $path); }

Answer 3

1. 检查所有变量的内容，看看它们是否包含任何东西（好）
2. 检查您要放置文件的目录是否存在，并且是否可由网络服务器（或运行 PHP 进程的人）写入。
3. 这是您从表单中调用的脚本吗？Apache 仅在调用脚本期间保留上传的文件，之后，如果文件未由脚本处理，则文件将被删除。
