Question

我无法移动上传的文件，问题似乎是权限问题，任何帮助都会非常感激。我使用的是Windows 10，我将php.ini中的临时文件夹更改为xampp目录中的自定义文件夹，当我检查此临时文件夹时，文件也不存在，所以看起来似乎它甚至没有上传到他们的临时状态。请帮忙。

Answer 1

如果文件尚未移走或重命名，该文件将在请求结束时从临时目录中删除。

Answer 2

问题似乎是我的方法而不是与权限有关。我当时正在使用存储在会话中的值传递给move_uploaded_file（）函数，一旦我直接从POST请求执行它就可以正常工作。是否需要从POST请求调用move_uploaded_file（）？任何人都想关注这一点，请做，因为我很想知道幕后发生的事情。
