PHP implementation of simple and practical pagination class code, simple and practical paging

This paper describes the simple and practical PHP implementation of the paging class. Share to everyone for your reference, as follows:

<?php class Page {private $total;  Total Records private $pagesize;     How many private $limit are displayed per page;      Limit private $page;   Current page number private $pagenum;      Total page number private $url;   Address private $bothnum;      On both sides keep the number of paging amount//Construction method Initialize Public function __construct ($_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; }//Gets the current page number private function Setpage () {if (!empty ($_get[' page '))) {if ($_get[' page '] > 0) {i          F ($_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. = ' URL. ' &page= '. $_page. ' " > '. $_page. '     ';  } $_pagelist. = ''. $this->page. '';        for ($i =1; $i <= $this->bothnum; $i + +) {$_page = $this->page+ $i;        if ($_page > $this->pagenum) break; $_pagelist. = ' URL. ' &page= '. $_page. ' " > '. $_page. '     ';   } return $_pagelist; }//Home Private Function First () {if ($this->page > $this->bothnum+1) {return ' URL.     >1 ... '; }}//prev Private Function prev () {if ($this->page = = 1) {return 'Previous Page'; } return ' URL. ' &page= '. ($this->page-1). ' "   > previous page '; }//Next Private Function next () {if ($this->page = = $this->pagenum) {return 'Next Page'; } return ' URL. ' &page= '. ($this->page+1). ' "   > next page '; }//End Private Function last () {if ($this->pagenum-$this->page > $this->bothnum) {return ' ... URL. ' &page= '. $this->pagenum. ' " > '. $this->pagenum. '     ';     }}//Paging information public Function showpage () {$_page. = $this->first ();     $_page. = $this->pagelist ();     $_page. = $this->last ();     $_page. = $this->prev ();     $_page. = $this->next ();   return $_page; }}?>

The paging style looks like this:

Instructions for use:

<?php  $_page = new page ($_total,$_pagesize);  Where $_total is the total number of data sets, $_pagesize is the number displayed per page. >
