Hello Ashley,

By  the  way,  the  non-last  optional parameter can't be missed, am I
right? In some languages we could write something like:
function test ($a, $foo=50, $bar=true) {
// ...

Then call it like this:

$m=test("blah", , false);


$m=test("blah", 50, false);
This is impossible in PHP, isn't it?

function load_advertisement( $web_page_reference ,

This sets a default value for a parameter, which you can check for
within the function itself and use it if it differs from what you set.
Set it to something that it shouldn't be, like null or something.

Also note that these parameters have to occur after any that don't have
a default value
