When using functions such as mysqli_num_rows() in the tp5.1 framework, an error will be reported. Can these functions not be used on TP?

Now they are all object-oriented-new mysqli or pdo

I queried the database before and found that the IDs were out of order, so I wanted to sort them using a cursor or something. Do you know any way to do this?

DB_TYPE is set to mysqli

Thank you very much for your reply. In which file is the configuration you are talking about located?

I changed the database link type in the database.php file and changed mysql to mysqli but still reported an error that the class does not exist: \think\db\connector\Mysqli. After checking the reason, it seems that tp5.1 does not support it. Before tp5, just change it to mysqli.
