Move_uploaded_file() not showing temp_name and others field in php 8.1

Question

After Upgrading to php 8.1 my move_uploaded_file function is not working. Tmp_name is empty and showing Error 6.

I am using PHPExcel. When I uploading it manually my data is fetching correctly but with using moveuploadedfunction the file is not moving to the folder. I increase the size of upload file and max post size in php.ini file. Below is the screenshot where tempname and size is showing zero.

Answer 1

The solution that work for me is. Granted the Full control rights to "C:\Windows\Temp".
