Php solves the problem of discovering all the data pagination class _ php instances in the old system

The difference is that the paging system is not implemented, by default, all of the results are displayed and cannot be moved to the background. You can use the following code to add several custom methods for extracting specified fragments from the mysql result set, the reason for not calling release involves the original verification of the program.
Thanks to the help of the online experts .... The old system kills people, and the background cannot be moved.

The Code is as follows:

/* Paging class
