問題描述

如何將同一個文件復制兩次?我正在嘗試做這樣的事情:

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");

臨時文件在被服務器銷毀之前有多少時間?

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

我也嘗試使用 move_uploaded_file，但我無法讓它工作.我想從上傳的文件中生成 2 個拇指.

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

需要幫助嗎?

謝謝，

推薦答案

move_uploaded_file 將移動文件，而不是復制它——這意味著它只能工作一次.

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

如果你使用copy，應該沒有任何限制完全取決于您可以復制的次數:上傳創建的臨時文件只會在腳本執行結束時被銷毀(除非您之前移動/刪除它，當然)

不過，也許解決方案是先使用 move_uploaded_file ，然后使用 copy ?
有點像，我想:

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');
}

這將允許您獲得 move_uploaded_file...

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

如果這不起作用，那么請確保:

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

• $folder 包含你想要的——包括最終的 /
• 那個$file['tmp_name'] 也包含你想要的(我猜這是$_FILES 的某種副本——make確保 $_FILES 到 $file 的副本正確完成)

• $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)
