When I was working with the localhost PHP database. so, I have encountered this kind of warning error on my PHP database. if you have no idea how to deal with this concern and how to fix it.
So, I have a simple solution and idea for this issue:
- First, Run your xampp web server
- Go to the xampp folder, xampp\mysqli\bin
- Run your mysqli_upgrade.exe
- After running mysqli_upgrade.exe, you will close and Restart the xampp and enjoy.
It really works for me and it will absolutely work for you.
