PHP实现对数组分页处理实例详解

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

  $this->pageArray=$arr['pageArray'];

  $this->pageSize=$arr['pageSize'];

 }else{

  return;

 }

 }

 //返回链接

 functionpage(){
