PHP to implement a simple and practical page-type code _php skills

The examples in this article describe the simple and practical application of the paging class in PHP. Share to everyone for your reference, specific as follows:

<?php class Page {private $total;  Total record private $pagesize;     How many private $limit to display per page;      Limit private $page;   Current page number private $pagenum;      Total page number private $url;   Address private $bothnum;  The volume//construct method of maintaining digital pagination on both sides initializes the public function __construct ($_total, $_pagesize) {$this->total = $_total? $_total:
     1;
     $this->pagesize = $_pagesize;
     $this->pagenum = ceil ($this->total/$this->pagesize);
     $this->page = $this->setpage (); $this->limit = "Limit".
     ($this->page-1) * $this->pagesize. ", $this->pagesize";
     $this->url = $this->seturl ();
   $this->bothnum = 2;
   }//Interceptor Private Function __get ($_key) {return $this->$_key;
          //Get current page number Private function Setpage () {if (!empty ($_get[' page ')) {if ($_get[' page '] > 0) {
          if ($_get[' page '] > $this->pagenum) {return $this->pagenum; else {REturn $_get[' page '];
        } else {return 1;
     } else {return 1;
     }//Get address Private Function SetUrl () {$_url = $_server["Request_uri"];
     $_par = Parse_url ($_url);
        if (isset ($_par[' query ')) {parse_str ($_par[' query '],$_query);
        unset ($_query[' page ')); $_url = $_par[' path '.
     Http_build_query ($_query);
   return $_url; }//Digital directory Private Function PageList () {for ($i = $this->bothnum; $i >=1; $i-) {$_page = $this->page-
      $i;
        if ($_page < 1) continue; $_pagelist. = ' <a href= '. $this->url. ' &page= '. $_page. ' " > '. $_page. '
     </a> '; $_pagelist. = ' <span class= ' me ' > '. $this->page. '
     </span> ';
        For ($i =1 $i <= $this->bothnum; $i + +) {$_page = $this->page+ $i;
        if ($_page > $this->pagenum) break; $_pagelist. = ' <a href= '. $this->url. ' &page= '. $_page. ' " > '. $_page.'
     </a> ';
   return $_pagelist; //Home Private Function First () {if ($this->page > $this->bothnum+1) {return ' <a href= ' . $this->url. ' "
     >1</a> ... '; }//previous Private Function prev () {if ($this->page = = 1) {return ' <span class= ' disabled ' >
     Previous page </span> '; Return ' <a href= '. $this->url. ' &page= '. ($this->page-1). "
   > Prev </a> '; //Next page Private function next () {if ($this->page = = $this->pagenum) {return ' <span class= ' di
     sabled "> Next page </span>"; Return ' <a href= '. $this->url. ' &page= '. ($this->page+1). "
   > next page </a> '; //End Private Function last () {if ($this->pagenum-$this->page > $this->bothnum) {retur N ' ... <a href= '. $this->url. ' &page= '. $this->pagenum. ' " > '. $this->pagenum. '
     </a> '; //Paging Information public function ShowpagE () {$_page. = $this->first ();
     $_page. = $this->pagelist ();
     $_page. = $this->last ();
     $_page. = $this->prev ();
     $_page. = $this->next ();
   return $_page;

 }}?>

The pagination style is shown in the following illustration:

Instructions for use:

<?php
  $_page = new page ($_total,$_pagesize);
  Where $_total is the total number of bars in the dataset, $_pagesize is the number of display per page.
