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
    /*
    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"];
    */
    ?>
