PHP实现对数组分页处理实例详解

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

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

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

$r = $arrayPage->page();
