Where does PHP save temporary files during uploading?
提问by powerboy
I am using XAMPP on Windows. By printing $_FILES["file"]["tmp_name"], it seems that the temporary file was saved at C:\xampp\tmp\phpABCD.tmp. But I cannot see it on the filesystem of the server. However, the file can be moved or copied via move_uploaded_file(), rename(), or copy(). So where does PHP actually save temporary files during uploading?
我在 Windows 上使用 XAMPP。通过打印$_FILES["file"]["tmp_name"]，似乎临时文件保存在 C:\xampp\tmp\phpABCD.tmp。但是我在服务器的文件系统上看不到它。但是，文件可以移动或复制通过move_uploaded_file()，rename()或copy()。那么PHP在上传过程中实际上将临时文件保存在哪里呢？

It saves it at the path specified in $_FILES["file"]["tmp_name"], but deletes it after the script is done executing. It's up to you to move the file elsewhere if you want to preserve it.
它将其保存在 中指定的路径中$_FILES["file"]["tmp_name"]，但在脚本执行完成后将其删除。如果您想保留文件，则由您将文件移到别处。

Its specified in upload_tmp_dirin your php.ini file. It is deleted by the system automatically after use.
它upload_tmp_dir在您的 php.ini 文件中指定 。使用后由系统自动删除。

You can check where php is currently saving your temp files $_FILES["file"]["tmp_name"]by printing
您可以files $_FILES["file"]["tmp_name"]通过打印来检查 php 当前保存您的临时文件的位置
sys_get_temp_dir()

Use move_uploaded_file(file, path), specify the file and the path where you want to store the file.
使用move_uploaded_file(file, path)，指定文件和要存储文件的路径。
A copy of that file is created and gets stored.
创建并存储该文件的副本。

php stores all temporary files, that includes uploaded files, in the temporary files directory as specified in the php.ini. Note that for uploads, those files might be removed as soon as the script the file was uploaded to was terminated (so unless you delay that script, you probably won't see the uploaded file). Another reason might be that the file is simply hidden on the file system.
php 将所有临时文件（包括上传的文件）存储在 php.ini 中指定的临时文件目录中。请注意，对于上传，一旦文件上传到的脚本终止，这些文件可能会被删除（因此除非您延迟该脚本，否则您可能看不到上传的文件）。另一个原因可能是该文件只是隐藏在文件系统中。
So if you want to see the file, you might want to make sure you see all hidden files in the explorer and delay the script as long as you need to find the file.
因此，如果您想查看该文件，您可能需要确保在资源管理器中看到所有隐藏文件，并在需要查找文件时延迟脚本。
