php array 分页代码示例

$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;
}
