基本的PHP表单帮助(货币显示)

Question

你们昨天非常有帮助.不过我在这里仍然有点困惑.

我想这样做,以便最右边一列的数字四舍五入到最接近的美元:

http://www.nextadvisor.com/voip_services/voip_calculator.php?monthlybill=50&Submit=Submit

该表的代码如下所示:

我想要$ offer [1,2,3,4,5,6,7] calcsavingsann四舍五入,怎么办呢？

 <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>
