A simple and pure PHP paging class

Jul 25, 2016 am 08:42 AM

Its characteristics: simple, accepts parameters and gives pagination; flexible: you can decide by yourself. The names of the previous and next pages (for example, I want to call them prev, next, etc.) can determine the number of paginations displayed on each page and the number of cross-pages. Provide a packaging method to adapt to different web page structures. For example, for some web pages, I need each page to contain a li(

  • 1
  • ...), and so on. Note: There are two static methods in the provided sample code, which you can ignore. This is for my own project development. Call::import, you can use include instead of URL::refresh. This is an address operation class. I will not explain it here for now. I will put it up when I have the opportunity. You can use the method getUrl() on this page http://www. oschin a.net/code/snippet_182375_6242
