php数组array函数实现php分页

3. //php分页代码
4. $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
5. $page= $_GET['page'];
6. $r = $this->page($array,5,$page);
7. print_r($r);
8. exit();
9. foreach($r["source"] as $s){
10. echo $s;
11. }
12. function page($array,$pagesize,$current){
13. $_return=array();
14. $total=ceil(Count($array)/$pagesize);//求总页数
15. $prev=(($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
16. $current=($current>($total)?($total):$current);//当前页如果大于总页数，当前页为最后一页
17. $start=($current-1)*$pagesize;//分页显示时，应该从多少条信息开始读取
18. for($i=$start;$i array_push($_return,$array[$i]);//将该显示的信息放入数组 $_return 中
19. }
20. $pagearray["source"]=$_return;
21. $pagearray["page"]="first \">prev next end";//分页样式可跟据需要调整
22. return $pagearray;
23. }
