Question

你们昨天很有帮助。不过我仍然有点困惑。

我想把右侧栏的数字四舍五入到最接近的整数美元。

将此翻译成中文：http://www.nextadvisor.com/voip_services/voip_calculator.php?monthlybill=50&Submit=Submit http://www.nextadvisor.com/voip_services/voip_calculator.php?monthlybill=50&Submit=Submit

这个表格的代码看起来像这样：

我想将$offer[1,2,3,4,5,6,7]calcsavingsann四舍五入，我该怎么做？

 <table width="100%;" border="0" cellspacing="0" cellpadding="0"class="credit_table2" >

    <tr class="credit_table2_brd">
     <td class="credit_table2_brd_lbl" width="100px;">Services:</td>
<td class="credit_table2_brd_lbl" width="120px;">Our Ratings:</td>
<td class="credit_table2_brd_lbl" width="155px;">Monthly VoIP Bill:</td>
<td class="credit_table2_brd_lbl" width="155px;">Annual Savings:</td>

   </tr>

Answer 1

您想将金额四舍五入/舍去小数/保留整数到最接近的一美元吗？

这里是您可以使用的一些建议功能：

四舍五入

round（舍入）

地板函数

向上取整

格式化/截断

sprintf

Answer 2

Grepseadawk的回答非常好，我要补充的是，你可以使用number_format来输出$336.60，而不是仅仅显示$336.6。

我知道这不是你的问题，但看了链接，我想这可能对你有用。

编辑 - 感谢安迪建议使用 money_format。

Answer 3

money_format() 是一个函数，返回格式化数字的字符串值。您可以控制格式和数字。一个简单的例子，如果您的值存储在变量$myNumber中，您可以将结果合并到给定表格的数据单元格中，例如：

<?php echo ("<td>".money_format( %n ,$myNumber)."</td>"); ?>

And you would need to do this for every value, e.g. via a for loop if you had all your values in an array. The n here is one of the formatting options - there are several. A good place to look would be on the PHP web page at http://au2.php.net/manual/en/function.money-format.php Hope this helps.

Answer 4

我似乎无法正确使用。我使用echo的方法是：

echo  <tr >

  <td ><a href=" .$offerlink. " target="blank"><img src="http://www.nextadvisor.com .$offerlogo. " alt=" .$offername. " /></a></td>

 <td ><span class="rating_text">Rating:</span><span class="star_rating1"><img src="http://www.nextadvisor.com .$offerstar. " alt="" /></span><br />

  <div style="margin-top:5px; color:#0000FF;"><a href=" .$offerlink. " target="blank">Go to Site</a><span style="margin:0px 7px 0px 7px;">|</span><a href=" .$offeranchor. ">Review</a></div>   </td>

  <td >$ .$offerprice. </td>

<td >$ .$offercalcsavingsann. </td>


   </tr> ;

我把“设置地区”放在那里

 "<?php"

我不明白如何写它，而且我用的每种方法都返回错误。
