这篇文章主要介绍了PHP实现对数组分页处理,结合实例形式分析了php封装的数组分页类定义与使用技巧,需要的朋友可以参考下

本文实例讲述了PHP实现对数组分页处理方法。分享给大家供大家参考，具体如下：

最近用到了用数组数据分页，这里整理了一下，具体代码如下：

									<?php

									class PaginationArray{

									 public $pageArray=array(); //数组

									 public $pageSize=10; //每页显示记录数

									 public $current= 1; //当前页

									 private $total=0; //总页数

									 private $prev=0; //上一页

									 private $next=0; //下一页

									 public $argumetsOther='';//设置参数

									 function __construct($array=array(),$pageSize=10,$current=1){

									 $this->pageArray=$array;

									 $this->pageSize=$pageSize;

									 $this->current=$current; 

									 }

									 /*通过数组进行初始化

									 * 

									 * 数组为关联数组,参数索引为pageArray,pageSize,current

									 * 

									 */

									 function setArguments($arr){

									 if (is_array($arr)){

									  $this->pageArray=$arr['pageArray'];

									  $this->pageSize=$arr['pageSize'];

									  $this->current=$arr['current'];

									 }else{

									  return ;

									 }

									 }

									 //返回链接

									 function page(){

									 $_return=array();

									 /*calculator*/

									 $this->total=ceil(Count($this->pageArray)/$this->pageSize);

									 $this->prev=(($this->current-1)<= 0 ? "1":($this->current-1));

									 $this->next=(($this->current+1)>=$this->total ? $this->total:$this->current+1);

									 $current=($this->current>($this->total)?($this->total):$this->current);

									 $start=($this->current-1)*$this->pageSize;

									 $arrleng=count($this->pageArray);

									 for($i=$start;$i<($start+$this->pageSize);$i++){

									  if($i >= $arrleng)break;

									  array_push($_return,$this->pageArray[$i]);

									 }

									 $pagearray["source"]=$_return;

									 $pagearray["links"]=$this->linkStyle(2);

									 return $pagearray;

									 }

									 //链接的样式

									 private function linkStyle($number=1){

									 $linkStyle='';

									 switch ($number){

									  case 1:

									  $linkStyle="<a href=\"?page=1\">first</a> <a href=\"?page={$this->prev}\">prev</a> <a href=\"?page={$this->next}\">next</a> <a href=\"?page={$this->total}\">end</a>";

									  break;

									  case 2:

									  $linkStyle="<a href=\"?page=1&{$this->argumetsOther}\">首页</a> <a href=\"?page={$this->prev}&{$this->argumetsOther}\">上一页</a> <a href=\"?page={$this->next}&{$this->argumetsOther}\">下一页</a> <a href=\"?page={$this->total}&{$this->argumetsOther}\">尾页</a>";

									  break;

									 }

									 return $linkStyle;

									 }

									}

									//调用的实例

									/*

									header('Content-Type: text/html;charset=utf-8');

									$array=array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20");

									$page= isset($_GET['page'])? $_GET['page'] : 1 ;

									$arrayPage = new PaginationArray($array,"5",$page);

									$r = $arrayPage->page();

									foreach($r["source"] as $s){

									 echo $s.'<br />';

									}

									echo $r["links"];

									*/

									?>
