No I did not get this sort of output
I got a parse error together with the correct outcome

when I removed the comments it was no longer given this error.
when I placed the // inside the comments /*

*/ I got the correct output of the program but it was repeated three times

here is the offending code, perhaps you can try it

it is the function.php file content please try it with and without the // inside the comments

<html>
<head><title>Calculating the purchase price</title></head>
<body>
<!--INSERT CODE HERE-->


<?php
$price = $_POST['price'];
$items = $_POST['items'];
//So, always use $whatever=$_POST['the_formarea_input']; when using forms.
function total ($price, $items)
{
$cost = $price * $items;
echo "the total price is $$cost";
}

echo total($price,$items);
?>


/*
libby - $cost=$_POST['cost']; is not going to bring you anywhere - cost was not passsed from cost.html to functions.php.
price and items were.

Note: the $ meant as a dollar as here above could cause problems. Better to print it outside php, like:

<?php
$price=$_POST['price'];
$items=$_POST['items'];

//function total($price, $items)
{
$cost=$price* $items;echo "the total price is"; ?>$<?php echo "$cost";}

echo total($price,$items);
?>
*/

</body>
</html>

Please put the code you want me to test inside two "containers" like

<---from here ---->

your code to test

<----to here ----->

since the code here above is deurmekaar. Did you mean to include the bottom part (between the /* */ comments?)

If so, then its wrong, since /* comments */ should be inside <?php ?> tags.

Comments, used OUTSIDE PHP tags, are done like this
<!-- comment-->

Comments, used inside PHP tags, are done like this
/* comment*/

or

// comment
