php 使用array函数实现分页

代码很简单，就不多废话了。$array=array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","1

代码很简单，就不多废话了。

$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;
 }

以上就是使用array函数实现分页的核心代码了，希望大家能够喜欢。
