php时间戳怎么转天数

php时间戳转天数的方法：首先创建一个php示例文件；然后通过“(time()-$v['createtime'])/86400;”方式将时间戳转为天数即可。

本文操作环境：Windows7系统、PHP7.1版，DELL G3电脑

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[&#39;logo&#39;]}">
<div class="mui-media-body">
{$v[&#39;title&#39;]}
<p class=&#39;mui-ellipsis&#39;>已坚持<span>
<?php
$times= (time()-$v[&#39;createtime&#39;])/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[&#39;title&#39;]} =<?php  echo $v[&#39;title&#39;];  ?>

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
