PHP实现对数组分页处理实例详解

<?phpclass 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 ?
