PHP page number form paging function supports static address and Ajax paging _php tips

Before each encounter pagination, always have to write their own, feel very cumbersome, so in accordance with the principle of general, wrote a pagination method, hereby record.

This page currently supports the Ajax paging (but JS has to write itself) for static address paging and no link addresses:

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

Other forms of statics need to be rewritten according to their own circumstances

AJAX-enabled paging, the $link parameter is NULL, but provides PID and Optype, where PID is used to get the page number, and optype to distinguish between the current trigger action and which paging logic is used when a page has multiple paging

Copy Code code as follows:

/**********************************************************
*
* Get page number
*
**********************************************************
*
* @params string $link link address (you can flip it with Ajax when the link is empty)
*
* @params int $intPage Current page
*
* @params int $intTotal Total pages
*
* @params int $intSize number of pages to display
*
* @params string $type chain inoculation class (multiple paging for distinguishing page-flipping area)
*
**********************************************************
*
* @return Array
