A "common" query paging class that can be used to query all tables

A "general" query page class that can query all tables. a "general" query page class that can query all tables has a recent whim. I hope to write a paging class that can be used to query all tables. In actual development, I am afraid that the most frequently used code is to query and display the result set by page, while the table structure is diverse, I want to improve the code reuse rate and maintainability as much as possible.
The following is my description. please give us some advice and test it to see if it can be improved or supported.
Currently, only a single table is supported, and joint query is not supported. However, we may consider how to support it in the future.

Code:
/*************************************** *************************
This class is mainly used to solve simple data queries targeting many tables and is still being improved. I hope the majority of users will give more comments and suggestions.

My goal is to develop a class that can be used to query almost all mysql tables and pagination the result set.
You can automatically identify the field values to be displayed in the query.

Here, I would like to express my special thanks to chinaunix friends, especially PHP netizens, for their long-term help.
He has always given me selfless help, even his source code.

This class can be freely referenced, used, modified by anyone. However, keep this text.
All the losses caused by using this class are irrelevant to the author tonera.

I am still considering that for some complex union queries, a class can be derived to reconstruct the SQL implementation.
This class does not consider more display styles. you can construct it yourself.
