问题描述

我怎样才能复制两次相同的文件?我试图做这样的事情:

$ $ p $ $ codeopy $($ file ['tmp_name'],$ folder。 JPG);
copy($ file ['tmp_name'],$ folder。2.jpg);
copy($ file ['tmp_name'],$ folder。3.jpg);

临时文件在被服务器销毁之前已经有多少次了?



我也尝试使用move_uploaded_file,但是我无法使它工作。我想从上传的文件中生成2个大拇指。

有些帮助吗?

感谢,

解决方案

move_uploaded_file 将移动文件,而不是复制它 - 这意味着它只能工作一次。



如果您使用 copy ,复制次数不应该有任何限制:由上传创建的临时文件只会在脚本执行结束时被销毁(当然,除非您之前移动/删除它)



另外,也许一个解决方案是首先使用 move_uploaded_file ,然后 copy ?

有点像,我想:

  if(move_uploaded_file($ file ['tmp_name'] ,$ folder。'1.jpg')){
copy($ folder。'1.jpg',$ folder。'2.jpg');
copy($ folder。'1.jpg',$ folder。'3.jpg');



$ b $ p
$ b

这将允许你得到 move_uploaded_file ...





如果这不起作用,请确保:


$ b

  • $文件夹包含您想要的内容 - 包括最后的 /

  • $ file ['tmp_name'] 也包含你想要的东西猜测这是 $ _ FILES 的副本 - 确保 $ _ FILES 的副本为 $ file 正确完成)


how can I copy two times the same file? I'm trying to do something like this:

                copy($file['tmp_name'], $folder."1.jpg");
            copy($file['tmp_name'], $folder."2.jpg");
            copy($file['tmp_name'], $folder."3.jpg");

And how many time does temp files has before it's destroyed by the server?

I try using move_uploaded_file also, but I can't make it work. I want to generate 2 thumbs from an uploaded file.

Some help?

Thanks,

解决方案

move_uploaded_file will move the file, and not copy it -- which means it'll work only once.

If you are using copy, there shouldn't be any limit at all on the number of times you can copy : the temporay file created by the upload will only be destroyed at the end of the execution of your script (unless you move/delete it before, of course)


Still, maybe a solution would be to use move_uploaded_file first, and, then, copy ?
A bit like that, I suppose :

if (move_uploaded_file($file['tmp_name'], $folder . '1.jpg')) {
    copy($folder . '1.jpg', $folder . '2.jpg');
    copy($folder . '1.jpg', $folder . '3.jpg');
}

This would allow you to get the checks provided by move_uploaded_file...


If this doesn't work, then, make sure that :

  • $folder contains what you want -- including the final /
  • That $file['tmp_name'] also contains what you want (I'm guessing this is some kind of copy of $_FILES -- make sure the copy of $_FILES to $file is done properly)
