PHP 分页实现函数

function pagelist($page,$total,$pageSize,$lan){
	$pagetext=''; //输出页面字符串
	$totalPage = ceil($total/$pageSize); // 转换为整型 (总共多少页 = 总数 / 每页显示数量)

	}else{
		$pagestr = "<span>共 $totalPage 页 $total 条数据</span> ";

		$pagestrU='上一页';
		$pagestrN='下一页';
		$pagestrW='尾页';
		$pagestrT='跳转';
		$pagestrP='请输入页码！';
