php 时间戳转化成天数 四舍五入 整数

public function edit() {

global $_W; global $_GPC; $openid=$_W['openid']; $boards = pdo_fetchall('select b.id,b.logo,b.title,f.createtime from ' . tablename('ewei_shop_sns_board_follow') . ' f ' . ' left join ' . tablename('ewei_shop_sns_board') . ' b on f.bid = b.id ' . ' where f.uniacid=:uniacid and f.openid=:openid ', array(':uniacid' => $_W['uniacid'], ':openid' => $openid));

$boards = set_medias($boards, 'logo'); include $this->template(); }

//html 代码  

<div class="mtvc mm"> {loop $boards $k $v} <div> <img class="mui-media-object mui-pull-left" src="{$v['logo']}"> <div class="mui-media-body"> {$v['title']} <p class='mui-ellipsis'>已坚持<span> <?php $times= (time()-$v['createtime'])/86400; // echo $times."<br>"; if( $times<1){ echo "1"; }else{ echo round("$times"); } ?> </span>天</p> <img class="mui-media-object mui-pull-right imgdel" src="../addons/ewei_shopv2/plugin/sns/static/images/btndel.png" onClick="delItem(this, id)"/></br> </div> </div> {/loop} </div>

重点 

{$v['title']} =<?php  echo $v['title'];  ?> 

round() 函数对浮点数进行四舍五入。

例子

<?php
echo(round(0.60));
echo(round(0.50));
echo(round(0.49));
echo(round(-4.40));
echo(round(-4.60));
?>

输出：

1
1
0
-4
-5
