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
classPaginationArray{
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
*
*/
functionsetArguments($arr){
if(is_array($arr)){
$this->pageArray=$arr['pageArray'];
$this->pageSize=$arr['pageSize'];
$this->current=$arr['current'];
}else{
return;
}
}
//返回链接
functionpage(){
$_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$pagearray;
}
//链接的样式
privatefunctionlinkStyle($number=1){
$linkStyle='';
switch($number){
case1:
$linkStyle="<ahref=\"?page=1\">first</a><ahref=\"?page={$this->prev}\">prev</a><ahref=\"?page={$this->next}\">next</a><ahref=\"?page={$this->total}\">end</a>";
break;
case2:
$linkStyle="<ahref=\"?page=1&{$this->argumetsOther}\">首页</a><ahref=\"?page={$this->prev}&{$this->argumetsOther}\">上一页</a><ahref=\"?page={$this->next}&{$this->argumetsOther}\">下一页</a><ahref=\"?page={$this->total}&{$this->argumetsOther}\">尾页</a>";
break;
}
return$linkStyle;
}
}
//调用的实例
/*

$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;
$arrayPage=newPaginationArray($array,"5",$page);
$r=$arrayPage->page();
foreach($r["source"]as$s){
echo$s.'<br/>';
}
echo$r["links"];

?>
