Put loop of variables into single array with formatting (PHP)

Question

I have the following loop;
<?php
$i=1;
while($i<=$num_rows)
$tempquantity = "extra".$i."quantity";
$tempcomments = "extra".$i."comments";
$tempname = "extra".$i."name";
$tempprice = "extra".$i."price";
$$tempquantity = $_POST['extra' . $i . 'quantity'];
$$tempcomments = $_POST['extra' . $i . 'comments'];
$$tempname = $_POST['extra' . $i . 'name'];
$$tempprice = $_POST['extra' . $i . 'price'];
print "Extra name: " . $$tempname;
print "<br />";
print "Extra price: " . $$tempprice;
print "<br />";
print "Quantity required: " . $$tempquantity;
print "<br />";
print "Client comments: " . $$tempcomments;
print "<br /><br />";
  $i++;
?>
Which, since there are 3 rows, outputs the following;
Extra name: dfvgfddf
Extra price: 4
Quantity required: 67
Client comments: gtfh
Extra name: wewew
Extra price: 34
Quantity required: 45
Client comments: thtrt
Extra name: ewewe
Extra price: 43
Quantity required: 12
Client comments: gdfgg
What I want to be able to do is show the output above in a PHP email body variable, which I think this means that the loop of varaibles needs to be in one single array variable since coding in an email body variable is not allowed. How do I put a loop of variables like this into a single variable, and how to I keep the <br /> tags and names in front of the varaibles ('Extra name:' etc), so it looks as it should in the PHP email body?
Thanks in advance

Hi Murray,
This is the code that sends the email;
$to = "$renteremail";
$subject = "Request confirmation";
$headers = "Content-type: text/html; charset=iso-8859-1\r\n";
$headers .= "From: website";
$body = "
Your reference number is <strong>$rrnumber</strong>.
<br />
<br />
Below is a summary of your request details;
<br /><br /><strong>Accommodation name</strong>: $accomm_name
<br /><strong>Accommodation type</strong>: $accomm_type
<br /><strong>Board-type</strong>: $ptbt
<br /><strong>Max. capacity</strong>: $ptc
<br /><strong>Check-in date</strong>: $passdate
<br /><strong>Number of nights</strong>: $passnights
<br /><br /><strong>Renter's name</strong>: $rentername
if (mail($to, $subject, $body, $headers)) {$messagesent = 'yes';}
So the three loop items with their four respective variables should go at the end of the list of variables above after 'Renters name'.
I also need to put the variables generated by the loop into a single database feild, so if possible all should go into one variable.
Thanks
