Krappleby025,

I think the folowing will give you the outcome you are looking for.

<?php
$var = &quot;10.00&quot;;
$cur = &quot;$&quot;; // Currancy

print &quot;$cur$var&quot;;
// the following ? > ends the php script
?>

In addition.

<?php
$var = &quot;10.00&quot;;
$cur = &quot;$&quot;; // Currancy

print &quot;$$var&quot;;
// the following ? > ends the php script
?>

The above also works. Out of curiousity where does the variable containing the number.number get it's value? Is the variable set as an Integer? If so try using

settype($var, 'double');

Regards

Hi,

The var is a number, and you want to display it with 2 decimals... Try this:

<?
  $value = 10;
  echo &quot;The value is &quot;.number_format($value,2).&quot;\$&quot;;
?>

Terminating a session -I think that die(); does the trick!

Good luck §;O)

Number formatting in PHP can be achieved with number_format like dkdude recommended.
I would also look at these functions:

Just for completeness:

Ending a session is done with

session_destroy();

.
