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>
  {loop $boards $k $v}
  <div>
  <img src="{$v['logo']}">
  <div>
  {$v['title']}

  <p>  <?php
  $times= (time()-$v['createtime'])/86400;
  // echo $times."<br>";
  if( $times<1){
  echo"1";
  }else{
  echo round("$times");
  }
  ?>
  </span>天</p>
  <img src="../addons/ewei_shopv2/plugin/sns/static/images/btndel.png"/></br>
  </div>
  </div>
  {/loop}
  </div>
  重点
  {$v['title']} =<?phpecho $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
