Every time I encountered pagination before, I always had to write it myself, which seemed quite tedious, so based on the general principle, I wrote a pagination method and recorded it here.

Currently, this paging supports static address paging and ajax paging when there is no link address (but js must be written by yourself):

The supported static addresses are as follows: www.example.com/xxx- xxx-p1-xxxx-xx.html

Other forms of staticization need to be rewritten according to your own situation

When supporting ajax paging, the $link parameter is empty, but pid and optype are provided. Among them, pid is used to obtain the page number, and optype is used to distinguish which paging logic the current trigger action belongs to when there are multiple pages on a page

Copy code The code is as follows :

/***************************************************** ******
*
* Get page number
*
****************************** *****************************
*
* @params string $link link address (the link is empty You can use ajax to turn pages)
*
* @params int $intPage Current page number
*
* @params int $intTotal Total number of pages
*
* @params int $intSize Number of pages to be displayed
*
* @params string $type link type (multiple pages are used to distinguish page turning areas)
*
******* *************************************************** *
*
* @return array

if( ($intSize+2) >= $intTotal )
