php配置的临时文件中并没有上传的文件,为什么还能使用move_uploaded_file() 成功移动?

Question

Answer 1

已经move掉了

这个函数叫move_uploaded_file 不叫 copy_uploaded_file

---

The file will be deleted from the temporary directory at the end of the request if it has not been moved away or renamed.

感谢 @xelz 和其它回答问题的朋友
如过你不去移动上传的文件、那么该文件就会在脚本周期执行完毕后自动删除
