php array 分页

$array=array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20");//规定要分页的数组

$page= $_GET['page'];$r = $this->page($array,5,$page);PRint_r($r);exit();foreach($r["source"] as $s){echo $s;}

function page($array,$pagesize,$current){$_return=array();$total=ceil(Count($array)/$pagesize);//求总页数$prev=(($current-1)<=0 ? "1":($current-1));//确定上一页,如果当前页是第一页,点击显示第一页$next=(($current+1)>=$total ? $total:$current+1);//确定下一页,如果当前页是最后一页,点击下页显示最后一页$current=($current>($total)?($total):$current);//当前页如果大于总页数,当前页为最后一页$start=($current-1)*$pagesize;//分页显示时,应该从多少条信息开始读取for($i=$start;$i<($start+$pagesize);$i++){array_push($_return,$array[$i]);//将该显示的信息放入数组 $_return 中}$pagearray["source"]=$_return;$pagearray["page"]="<a href=\"?page=1\">first</a> <a href=\"?page={$prev}\">prev</a> <a href=\"?page={$next}\">next</a> <a href=\"?page={$total}\">end</a>";//分页样式可跟据需要调整return $pagearray;}
