Windows 10文件上传和权限php

Question

我在移动上传的文件时遇到了麻烦，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，我已经将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，该文件也不存在，所以似乎它甚至没有被上传到他们temp.请帮助。

Answer 1

如果该文件未被移走或重命名，则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请求中执行，它就工作得很好。是move_uploaded_file()需要从POST请求调用吗?如果有人想解释一下这个问题，请这样做，因为我很想知道幕后发生了什么。
