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"]; */ ?>
