A "common" query paging class in php that can query all tables

In php, a "general" query page class that can be used to query all tables is a "general" query page class that can be used to query all tables? In 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 .? I wrote the following: Please give me some advice to test a "common" query paging class in php that can query all tables.

What is the "general" query paging class that can be used to query all tables?
In 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 .?
I wrote the following: could you give me some advice and test it to see if you can make better improvements and support .?
Currently, only a single table is supported, and joint query is not supported. But how can we support it in the future .?
