basic php form help (currency display) - php

Question

You guys were very helpful yesterday. I am still a bit confused here though.
I want to make it so that the numbers on the rightmost column are rounded off to the nearest dollar:
http://www.nextadvisor.com/voip_services/voip_calculator.php?monthlybill=50&Submit=Submit
the code for the table looks like this:
I want $offer[1,2,3,4,5,6,7]calcsavingsann to be rounded, how can do this?
<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

Do you want rounded up/down/truncated to the nearest dollar?
Here are some suggested functions you can use:
Rounding
round
floor
ceil
Formatting/Truncating
sprintf

Answer 2

Grepsedawk's answer is good; the only thing I would add is that rather than displaying $336.6, for example, you could could use number_format to output $336.60.
(I know this wasn't your question, but looking at the link, I thought that might be useful for you.)
Edit - Thanks to Andy for suggesting money_format instead.

Answer 3

money_format() is a function that returns a string value of a formatted number. You have control over the formatting and, obviously, your number. A simple example, if you have your value in the variable $myNumber, you could incorporate the result into a given table's data cell like so;
<?php echo ("<td>".money_format('%n',$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

I can't seem to get the usage right. The way I am using echo is
echo '<tr >
<td ><img src="http://www.nextadvisor.com'.$offerlogo.'" alt="'.$offername.'" /></td>
<td ><span class="rating_text">Rating:</span><span class="star_rating1"><img src="http://www.nextadvisor.com'.$offerstar.'" alt="" /></span><br />
<div style="margin-top:5px; color:#0000FF;">Go to Site<span style="margin:0px 7px 0px 7px;">|</span>Review</div> </td>
<td >$'.$offerprice.'</td>
<td >$'.$offercalcsavingsann.'</td>
</tr>';
I put the "set locale" up where the
"<?php"
is. I don't understand how to write it, and every way I do just returns an error.
