  1. //php分页代码
  2. $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
  3. $page= $_GET['page'];
  4. $r = $this->page($array,5,$page);
  5. print_r($r);
  6. exit();
  7. foreach($r["source"] as $s){
  8. echo $s;
  9. }
  10. function page($array,$pagesize,$current){
  11. $_return=array();
  12. $total=ceil(Count($array)/$pagesize);//求总页数
  13. $prev=(($current-1) $next=(($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
  14. $current=($current>($total)?($total):$current);//当前页如果大于总页数,当前页为最后一页
  15. $start=($current-1)*$pagesize;//分页显示时,应该从多少条信息开始读取
  16. for($i=$start;$i array_push($_return,$array[$i]);//将该显示的信息放入数组 $_return 中
  17. }
  18. $pagearray["source"]=$_return;
  19. $pagearray["page"]="first \">prev next end";//分页样式可跟据需要调整
  20. return $pagearray;
  21. }
