php array 分页,array分页
php array 分页,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) $next=(($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 array_push($_return,$array[$i]);//将该显示的信息放入数组 $_return 中
}
$pagearray["source"]=$_return;
$pagearray["page"]="first \">prev next end";//分页样式可跟据需要调整
return $pagearray;
}
$listArr = array_slice($array, ($page-1)*$pagesize, $pagesize, true);
$page 为页数
这种不建议使用php分页,因为数据已经完整了,出于优化显示效果的目的而分页的话可以采用js方式。因为页面跳转需要让访问者等待较长的时间,所以不推荐这样做。
通常的分页都是将数据库内容进行分页,比如需要显示100条,但是每次只显示10条,这样一个是展示起来较快,另一个主要的原因是减少数据库端的压力。
你这种可以简单的分开放在多个div里面,通过上一页下一页控制div的显示和隐藏就行了。
